PST731xxB
300mA Ultra Low LDR LDO
General Description
The PST731xxB family of low-dropout (LDO), low-power linear
regulators offers high power supply
rejection ratio (PSRR) while maintaining very low 35A ground current.
The family uses an advanced CMOS process and a PMOSFET pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance.
The PST731xxB is
stable with a 1.
0F ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations.
It is fully specified from TJ = –40°C to +125°C and is offered in a small TSOT23-5 packa...
