LINEAR LT3150 handbook
The LT3150 is a fast transient response, low input voltage, very low dropout linear regulator controller. It is suitable for applications such as microprocessors, ASICs, and I/O supplies, logic termination supplies, etc. Its transient response is optimized with ceramic output capacitors and has a very low dropout voltage. By selecting the N-channel MOSFET RDS(ON), dropout voltages below 300mV can be achieved for low VIN to low VOUT applications. The LT3150 also includes a fixed frequency boost converter that generates gate drive for the N-channel MOSFET. The internally compensated current mode PWM architecture combined with the 1.4MHz switching frequency allows the use of tiny, low-cost capacitors and inductors. The LT3150 features a multifunction LDO shutdown pin with latchoff. The fixed frequency 1.4MHz boost converter generates MOSFET gate drive. The independent boost converter shutdown control permits LDO output voltage supply sequencing. The LT3150 is available in a 16-lead SSOP package.

LINEAR LT3021/LT3021-1.2/ LT3021-1.5/LT3021-1.8 handbook
The LT3021 is a low dropout voltage linear regulator that operates from input supplies down to 0.9V. It supplies 500mA of output current with a typical dropout voltage of 160mV. The LT3021 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator.
LINEAR LT3028 handbook
This document introduces the LT ®3028 3028f dual 100mA/500mA low dropout, low noise, micropower regulator with independent inputs. With an external 0.01μF bypass capacitor, output noise is a low 20μVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 30μA quiescent current per output makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1μA. Shutdown control is independent for each output, allowing for flexibility in power management. The device is capable of operating over an input voltage range of 1.8V to 20V. Output 1 can supply 500mA of output current with a dropout voltage of 320mV. The device can supply 100mA of output current from Output 2 with a dropout voltage of 300mV. Quiescent current is well controlled in dropout. The LT3028 regulator is stable over a 1.22V to 20V output voltage range with as little as 1µF/3.3µF output capacitor and with aluminum, tantalum, or ceramic capacitors. The device is reverse-battery protected, does not require protection diodes, and offers overcurrent and overtemperature protection. It also features tracking/sequencing capability. The LT3028 is available in thermally enhanced 16-Lead TSSOP and 16-Lead (5mm × 3mm) DFN packages.

The LTC3409 3409f is a high efficiency, monolithic synchronous buck regulator using a constant frequency, current mode architecture. It features 600mA output current, 1.6V to 5.5V input voltage range, 1.7MHz or 2.6MHz selectable frequency, low static current, low dropout, etc.
LINEAR LT3020/LT3020-1.2/ LT3020-1.5/LT3020-1.8 handbook
The LT ®3020 is a very low dropout voltage (VLDO TM) linear regulator that operates from input supplies down to 0.9V. This device supplies 100mA of output current with a typical dropout voltage of 150mV. The LT3020 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator. The LT3020 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 2.2µF. Other LT3020 features include 0% typical line regulation accuracy, 100mA of output current, and a 150mV typical dropout voltage.
LINEAR LT3014 handbook
LINEAR LT3012 handbook
The LT3012 is a high voltage, micropower low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (40µA operating and 1µA in shutdown) makes the LT3012 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3012 include the ability to operate with very small output capacitors. The regulators are stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available with an adjustable output.
