1 / 28 page LP2992 www.ti.com SNVS171G – NOVEMBER 2001 – REVISED MARCH 2013 LP2992 Micropower 250 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and WSON Packages Designed for Use with Very Low ESR Output Capacitors Check for Samples: LP2992 1 FEATURES DESCRIPTION The LP2992 is a 250 mA, fixed-output voltage 2 • Ultra Low Dropout Voltage regulator designed to provide ultra low-dropout and • Specified 250 mA Output Current low noise in battery powered applications. • Smallest Possible Size (SOT-23, WSON Using an optimized VIP (Vertically Integrated PNP) Package) process, the LP2992 delivers unequaled performance • Requires Minimum External Components in all specifications critical to battery-powered designs: • Stable with Low-ESR Output Capacitor • <1 µA Quiescent Current when Shut Down Dropout Voltage: Typically 450 mV @ 250 mA load, and 5 mV @ 1 mA load. • Low Ground Pin Current at all Loads • Output Voltage Accuracy 1% (A Grade) Ground Pin Current: Typically 1500 µA @ 250 mA load, and 75 µA @ 1 mA load. • High Peak Current Capability • Wide Supply Voltage Range (16V Max) Enhanced Stability: The LP2992 is stable with output capacitor ESR as low as 5 m Ω, which allows • Low ZOUT: 0.3Ω Typical (10 Hz to 1 MHz) the use of ceramic capacitors on the output. • Overtemperature/overcurrent Protection Sleep Mode: Less than 1 µA quiescent current when • −40°C to +125°C Junction Temperature Range ON/OFF pin is pulled low. • Custom Voltages Available Smallest Possible Size: SOT-23 and WSON packages use absolute minimum board space. APPLICATIONS Precision Output: 1% tolerance output voltages • Cellular Phone available (A grade). • Palmtop/Laptop Computer Low Noise: By adding a 10 nF bypass capacitor, • Personal Digital Assistant (PDA) output noise can be reduced to 30 µV (typical). • Camcorder, Personal Stereo, Camera Multiple voltage options, from 1.5V to 5.0V, are available as standard products. Consult factory for custom voltages.
