Product Summary

The LK112M50TR is a low dropout linear regulator with a built in electronic switch. The internal switch can be controlled by TTL or CMOS logic levels. The LK112M50TR is ON state when the control pin is pulled to a logic high level. An external capacitor can be used connected to the noise bypass pin to lower the output noise level to 30µVrms. An internal PNP pass transistor is used to achieve a low dropout voltage.

Parametrics

LK112M50TR absolute maximum ratings: (1)VI, DC Input Voltage: 16 V; (2)VSHDN Shutdown Input Voltage: 16 V; (3)IO Output Current; Internally limited; (4)Tstg Storage Temperature Range: -55 to +150℃; (5)Top Operating Junction Temperature Range: -30 to +125℃.

Features

LK112M50TR features: (1)output current up to 150mA; (2)low dropout voltage (350mV at Iout=150mA); (3)very low quiescent current: 0.1μA in off mode and max 250μA in on mode at Iout=0mA; (4)low output noise: typ 30μV at IOUT=60mA and 10Hz<f<80KHz; (5)wide range of output voltgaes; (6)internal current and thermal limit.
