This datasheet provides detailed information on the features and characteristics of the ZM4728A-ZM4764A, including power dissipation, rated voltage, forward voltage, and operating temperature range.

AP1533 is a PWM control 1.8A step-down converter with low ripple power, high efficiency and excellent transient characteristics. The converter contains a reference voltage source, oscillation circuit, error amplifier and internal PMOS. The PWM control circuit is able to vary the duty ratio linearly from 0% to 99%. The converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup. An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 300KHz to 50KHz. Also, an internal compensation block is built in to minimum external component count. With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with mobile devices.

The ZLDO Series low dropout linear regulators have an exceptionally low dropout voltage, typically only 30mV with a load current of 100mA. The regulator series features output voltages in the range 2.7 to 18 volts, and this device provides an output voltage of 4.85 volts. The ZLDO485 consumes a typical quiescent current of only 1mA and is rated to supply load currents up to 300mA. A battery low flag is available to indicate potential power fail situations. If the input voltage falls to within 200mV of the regulated output voltage, then the error output pulls low. The device also features an active high disable control. Once disabled, the ZLDO quiescent current falls to typically 11µA. The ZLDO devices are packaged in Zetex SM8 8 pin small outline surface mount package, ideal for applications where space saving is important. The device's low dropout voltage, low quiescent current, and small size make it ideal for low power and battery powered applications. Battery powered circuits can make particular use of the low battery flag and shutdown features.
