LP295x Adjustable Micropower Low-Dropout Voltage Regulators Features 3 DescriptionThe LP2952 and LP2953 are micropower voltage 2.3-Vto 30-V Input Voltage Range regulators with very low quiescent current (130 μA• Output Voltage Adjusts from 1.23Vto29V typicalat 1-mA load) and very low dropout voltage• 250-mA Output Current (typically 60 mVat light load and 470 mVat 250-mA
load current). They are ideally suited for battery-• Extremely Low Quiescent Current powered systems. Furthermore, the quiescent current• Low Dropout Voltage increases only slightly at dropout, which prolongs• Extremely Tight Line and Load Regulation battery life. Very Low Temperature Coefficient The LP2952 and LP2953 retain all the desirable• Current and Thermal Limiting characteristics of the LP2951, but offer increased
output current, additional features, and an improved• Reverse Battery-Input Protection
shutdown function.• 50-mA (Typical) Automatic Output Discharge
The automatic output discharge pulls the output down• LP2953 Versions Only
quickly when the shutdownis activated.– Auxiliary Comparator Included With CMOS-
and TTL-Compatible Output Levels. Can Be The error flag goes lowif the output voltage drops out regulation.Used for Fault Detection, Low-Input Line
Detection, andso on. Reverse battery-input protectionis provided.
The internal voltage referenceis made available for
2 Applications external use, providinga low temperature coefficient• High-Efficiency Linear Regulator (20 ppm/°C) reference with very good line (0.03%)
and load (0.04%) regulation.• Regulator With Undervoltage Shutdown Low-Dropout Battery-Powered Regulator
