Voltage Regulators

ST Microelectronics - L4960 Voltage Regulators, Switching.

The L4960 is a monolithic stepdown switching regulator providing output voltages from 5.1V to 40V and delivering 2.5A. The regulation loop consists of a sawtooth oscillator, error amplifier, comparator and the output stage. An error signal is produced by comparing the output voltage with a precise 5.1V on-chip reference (zener trimmed to ±2%).

ST Microelectronics - L4940V5 - Voltage Regulator.

The L4940 series of three-terminal positive regulators is available in TO-220 and D²PAK packages and with several fixed output voltages, making it useful in a wide range of industrial and consumer applications. Thanks to their very low input/output voltage drop, these devices are particularly suitable for battery-powered equipment, reducing consumption and prolonging battery-life. Each type employs internal current limiting, anti-saturation circuit, thermal shutdown and safe area protection.

Polarity: Positive.

Adjustment Range: 5V.

Maximum Current: 1.5Amp.

Package: TO-220 W/Trimmed and D formed leads/board ready.

Note: Very Low Drop.
