1 / 30 page  2017 - 2022 Microchip Technology Inc. and its subsidiaries DS20005736B-page 1 LP2951 Features • High Accuracy 5V, Guaranteed 100 mA Output • Extremely Low Quiescent Current • Low-Dropout Voltage • Extremely Tight Load and Line Regulation • Very Low Temperature Coefficient • Use as Regulator or Reference • Needs Only 1 μF for Stability • Current and Thermal Limiting • Error Flag Warns of Output Dropout • Logic-Controlled Electronic Shutdown • Output Programmable from 1.24V to 29V Applications • Automotive Electronics • Voltage Reference • Avionics General Description The LP2951 is micropower voltage regulators with very low dropout voltage (typically 40 mV at light loads and 380 mV at 100 mA), and very low quiescent current (75 μA typical). The quiescent current of the LP2951 increases only slightly in dropout, thus prolonging battery life. This feature, among others, makes the LP2951 ideally suited for use in battery-powered systems. Available system functions, such as programmable output voltage and logic-controlled shutdown, are available as well. Additional features available with the LP2951 also include an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logic-compatible shutdown input is also available which enables the regulator to be switched on and off. This part may also be pin-strapped for a 5V output, or programmed from 1.24V to 29V with the use of two external resistors. The LP2951 is available as either a -02 or -03 version. The -02 and -03 versions are guaranteed for junction temperatures from -40°C to +125°C; the -02 version has a tighter output and reference voltage specification range over temperature. The LP2951 have a tight initial tolerance (0.5% typical), a very low output voltage temperature coefficient which allows use as a low-power voltage reference, and extremely good load and line regulation (0.05% typical). This greatly reduces the error in the overall circuit, and is the result of careful design techniques and process control.
