LM723CN Voltage Regulator

Description

LM723CN Voltage Regulator The LM723CN is a versatile voltage regulator designed to serve as a precision, adjustable power supply, and current regulation device. It is capable of providing a stable output voltage from 2V up to 37V, with a maximum output current of 150mA internally, which can be enhanced with external pass transistors for higher currents. This makes it suitable for a broad range of applications, including power management in electronic systems, battery chargers, and adjustable power supplies. Features: Input Voltage Up to 40V. Output Voltage Adjustable From 2 to 37V. Positive or Negative Supply Operation. Series, Shunt, Switching or Floating Operation. Output Current to 150mA Without External Pass Transistor. ADJUSTABLE CURRENT LIMITING. Specifications: Type Programmable Voltage Regulator Package 14-lDIP Voltage – Input (Max) 40V Voltage – Output (Min/Fixed) 2V Voltage – Output (Max) 37V Current – Output 150mA Current – Quiescent (Iq) 4 mA Temperature Range 0°C ~ 70°C Dropout Voltage 3V Load Regulation 0.10% PSRR 86db ~ 74dB (100Hz ~ 10kHz) Frequency Compensation External network required Pin Configuration: NC: No connection.
