The UM1750S-00 is a fixed 5V low dropout regulator capable of delivering 350mA. It features a low quiescent current of 130 µA and an excellent dropout voltage of just 150mV at 150mA. With PSRR of 63dB at 100Hz, it provides clean power for audio and industrial applications. Packaged in SOT-23-5, it balances performance and size.
- Higher Current Capacity: 350mA output supports more demanding loads than typical 150mA LDOs.
- Excellent PSRR: 63dB at 100Hz rejects mains hum for audio and precision circuits.
- Very Low Dropout: 150mV at 150mA maximizes efficiency with tight input margins.
- Compact SOT-23-5: Easy to integrate into industrial and consumer designs.
