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 P
MOSFET 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 package, a tiny SC70-5 package, and a ultra-small 2mm × 2mm DFN package with a thermal pad, which are ideal for small form factor portable equipment such as wireless handsets and PDAs.
The PST731xxB is available in standard fixed output
voltages of 1.2V (PST73112B), 1.5V (PST73115B), 1.8V (PS...
