TS834 is a voltage supervisor with features of ultra low power consumption, precision reset threshold, fast response time, etc. It provides two different outputs, one active low and one active high.

The L79L00 series is a negative voltage regulator with internal current limiting and thermal shutdown functions, capable of delivering up to 100mA output current. They are intended for a wide range of applications, including local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation. Additionally, they can be used with power pass elements to create high-current voltage regulators.

The LD2981AB/C series are 100 mA fixed-output voltage regulators. The low drop-voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery powered systems.

The PB137 is a positive voltage regulator from ST company. Its rated output voltage is 13.7V and the maximum output current is 1.5A.

The TS831 is an ultra low power integrated circuit incorporating a high stability band-gap voltage reference and a comparator with an open drain output.

L4976 is a 1A step-down switching regulator with an input voltage range of 8V to 55V and an output voltage adjustable range of 0.5V to 50V. It is fabricated using BCD mixed technology and features an internal power D-MOS transistor with a typical Rds(ON) of 0.25Ω for very high efficiency and fast switching speed.

The LD2979 series are very low drop regulators available in SOT23-5L. The very low drop-voltage and the very low quiescent current make them particularly suitable for low noise, low power applications and in battery powered systems.

L4978 is a step down monolithic power switching regulator that delivers 2A output current between 3.3V and 50V. It features a wide input voltage range, adjustable output voltage, and adjustable switching frequency.

L4971 is a 1.5A step down switching regulator that delivers 1.5A at a voltage between 3.3V and 50V (selected by a simple external divider). Realized in BCD mixed technology, the device uses an internal power D-MOS transistor (with a typical Rdson of 0.25Ω) to obtain very high efficency and high switching speed.
