The Texas Instruments LP5951MGX-1.3/NOPB is a low-power LDO regulator delivering a fixed 1.3V output at up to 150mA. With a quiescent current of just 55µA and PSRR of 60dB at 100Hz, it provides clean, efficient power for battery-operated and noise-sensitive applications. The 350mV dropout at full load allows operation from low input voltages. Packaged in a compact SC-70-5, it is ideal for space-constrained portable electronics.
- Ultra-Low Quiescent Current: 55µA maximizes battery life in standby and active modes.
- Good Noise Rejection: 60dB PSRR at 100Hz filters low-frequency interference.
- Compact SC-70-5 Package: Small footprint for portable and wearable devices.
- Low Dropout: 350mV at 150mA supports low input voltage operation.
Low-Voltage Microcontroller Power
1.3V output is perfect for next-gen low-power MCUs operating at 1.2V-1.3V, with 55µA quiescent current supporting always-on modes.
