1 / 26 page LP2953QML, LP2953QML-SP www.ti.com SNVS395C – NOVEMBER 2010 – REVISED APRIL 2013 LP2953QML Adjustable Micropower Low-Dropout Voltage Regulators Check for Samples: LP2953QML, LP2953QML-SP 1 FEATURES DESCRIPTION The LP2953A is a micropower voltage regulator with 2 • Output Voltage Adjusts from 1.23V to 29V very low quiescent current (130 μA typical at 1 mA • Ensured 250 mA Output Current load) and very low dropout voltage (typ. 60 mV at • Extremely Low Quiescent Current light load and 470 mV at 250 mA load current). It is ideally suited for battery-powered systems. • Low Dropout Voltage Furthermore, the quiescent current increases only • Extremely Tight Line and Load Regulation slightly at dropout, which prolongs battery life. • Very Low Temperature Coefficient The LP2953A retains all the desirable characteristics • Current and Thermal Limiting of the LP2951, but offers increased output current, • Reverse Battery Protection additional features, and an improved shutdown function. • 50 mA (Typical) Output Pulldown Crowbar • Auxiliary Comparator Included with CMOS/TTL The internal crowbar pulls the output down quickly when the shutdown is activated. Compatible Output Levels. Can be used for Fault Detection, Low Input Line Detection, etc. The error flag goes low if the output voltage drops out of regulation. APPLICATIONS Reverse battery protection is provided. • High-Efficiency Linear Regulator The internal voltage reference is made available for • Regulator with Under-Voltage Shutdown external use, providing a low-T.C. reference with very • Low Dropout Battery-Powered Regulator good line and load regulation. • Snap-ON/Snap-OFF Regulator Connection Diagram Note: Pins 1, 8, 9, 16 must be shorted together on customer PC board application Figure 1. 16-Pin CFP Package 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
