1 / 22 page  LP2952/LP2952A/LP2953/LP2953A Adjustable Micropower Low-Dropout Voltage Regulators General Description The LP2952 and LP2953 are micropower voltage regulators with very low quiescent current (130 µA typical at 1 mA load) and very low dropout voltage (typ. 60 mV at light load and 470 mV at 250 mA load current). They are ideally suited for battery-powered systems. Furthermore, the quiescent cur- rent increases only slightly at dropout, which prolongs bat- tery life. The LP2952 and LP2953 retain all the desirable character- istics of the LP2951, but offer increased output current, additional features, and an improved shutdown function. The internal crowbar pulls the output down quickly when the shutdown is activated. The error flag goes low if the output voltage drops out of regulation. Reverse battery protection is provided. The internal voltage reference is made available for external use, providing a low-T.C. reference with very good line and load regulation. The parts are available in DIP and surface mount packages. Features n Output voltage adjusts from 1.23V to 29V n Guaranteed 250 mA output current n Extremely low quiescent current n Low dropout voltage n Extremely tight line and load regulation n Very low temperature coefficient n Current and thermal limiting n Reverse battery protection n 50 mA (typical) output pulldown crowbar n 5V and 3.3V versions available LP2953 Versions Only n Auxiliary comparator included with CMOS/TTL compatible output levels. Can be used for fault detection, low input line detection, etc. Applications n High-efficiency linear regulator n Regulator with under-voltage shutdown n Low dropout battery-powered regulator n Snap-ON/Snap-OFF regulator Block Diagrams LP2952 01112701 LP2953 01112702 March 2005 © 2005 National Semiconductor Corporation DS011127 www.national.com |
