Semtech SC560
Dual Output Low Noise LDO Linear Regulator
The SC560 is a family of dual output, ultra-low dropout linear voltage regulators designed for use in battery powered wireless applications. The SC560A, SC560B, and SC560C provide adjustable output voltages that can be set using two external resistors.
Features
- Input Voltage Range — 2.5V to 5.5V
- Output voltage Ranges — 1.2V to 3.3V (each LDO)
- Maximum Output Current — 300mA (both LDOs)
- Dropout at 200mA load — 200mV max.
- Quiescent Supply Current = 100μA (both LDOs enabled)
- Shutdown Current = 100nA (typ)
- Output Noise < 50μVRMS (SC560A and fixed output versions)
- PSRR < -65dB at 1kHz (SC560A and fixed output versions)
- Over-temperature protection
- Short-circuit protection
- Under-voltage lockout
- Power good monitor for output A (SC560C and fixed output versions)
- Independent enable/disable for LDOB (SC560B and fixed output versions)
- MLPQ-UT8, 1.5mm x 1.5mm x 0.6mm package
