TS5205

150mA Low Noise LDO Voltage Regulator

with Enable Function

1/7

Version: B07

SOT-25

General Description

TS5205 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at

light loads and 165mV at 150mA), 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. TS5205 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.
