TS5201

200mA Low Noise LDO

Voltage Regulator with Enable

1/7

Version: B07

SOP-8

General Description

TS5201 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at

light loads and 165mV at 200mA), and very low power consumption (600uA at 100mA), providing high output current

even when the application requires very low dropout voltage. The Chip Enable (EN) includes a CMOS or TTL

compatible input allows the output to be turned off to prolong battery life. When shutdown, power consumption drops

nearly to zero. TS5201 is included a precision voltage reference, error correction circuit, a current limited output

driver, over temperature shutdown, revered battery protection and a reference bypass pin to improve its already

excellent low-noise performance.
