The PST731xx family of low-dropout (LDO), low-power linear regulators offers very high power supply rejection ratio (PSRR) while maintaining very low 38mA 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 PST731xx is stable with a 1.0mF 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 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
PST731xx is available in standard fixed output voltages of 1.2V
(PST73112), 1.5V (PST73115), 1.8V (PST73118), 2.5V (PST73125),
2.8 (PST73128), 3.0V (PST73130), 3.3V (PST73133), and custom
voltage options (50mV step options between 0.8V and 5.0V are
available upon request).
