LDO Voltage Regulator TSMC 28nm
The 1.8V LDO (PMOS pass device) is a low drop out linear voltage regulator; the 0.9V LDO (NMOS pass device) is a low drop out linear voltage regulator; both are designed in TSMC28HPC/HPC+ technology. They can sustain up to 1.98V power supply and provide high accuracy output voltage for dedicated applications. It embeds an UVLO monitoring function to alert digital when power supply fall below programmable threshold.
Features
- Vin=1.9V supply LDO NMOS (0.9V/20mA) & LDO PMOS (1.8V/50mA)
- 50mA nominal current for LDO PMOS
- 20mA nominal current for LDO NMOS
- Vin up 1.98V power supply (AVDD) for both LDOs
- Programmable output Voltage for both LDOs
- VOUTOK monitoring VOUTLDO (both 1.8V & 0.9V outputs)
- 1µF (for LDO PMOS) & 220nF (for LDO NMOS) external cap
- 100mV drop for LDO PMOS
- 150mA for LDO PMOS & 60mA for LDO NMOS Current limit protection
- Low DC PSRR
