NJM723 PRECISION VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJM723 is a Precision Monolithic Voltage Regulator. The device consists of a temperature-compensated Voltage reference, error amplefier, power-series pass transistor and current-limit circuitry. Additional NPN or PNP pass elements may be used when output currents exceeding 150mA are required. In addition to the above, the device features low standby current drain, low temperature drift and high ripple rejection. The NJM723 is intended for use with positive or negative supplies as a series, shunt, switching of floating instrument power supplies, and other power supplies for digital and linear circuits. ■ PACKAGE OUTLINE NJM723D NJM723M NJM723V ■ FEATURES • Operating Voltage (12V to 40V) • 150mA output current without external pass transistor • Output currents in excess of 10A posible by adding external • Input voltage 40V max • Output voltage adjustable from 2V to 37V • Can be used as elther a linear or a switching regulator. • Package Outline DIP14, DMP14, SSOP14 • Bipolar Technology ■ PIN CONFIGURATION NJM723D NJM723M NJM723V ■ EQUIVALENT CIRCUIT Ver.2003-07-18 -1- NJM723 ■ ABSOLUTE MAXIMUM RATINGS PARAMETER (Ta=25°C) SYMBOL RATINGS UNIT + Supply Voltage V /V - 40 V Drpout Voltage ∆VIO 40 V VIN (diff) ±5 V Output Current IO 150 mA Power Dissipation PD (DIP8) 700 (DMP8) 700 (note) (SSOP8) 450 (note) mW mW mW Current from VREF IREF (VREF) 15 mA Operating Temperature Range Topr -20 to +75 ºC Storage Temperature Range Tstg -40 to +125 ºC Differential Input Voltage (note) At on PC board ■ ELECTRICAL CHARACTERISTICS PARAMETER Line Regulation SYMBOL ∆VIO - VIN Load Regulation ∆VO - VO Ripple Rejection RR Average Temperature Coefficient of Output Voltage (Ta=25ºC, V+=Vc=12V, V-=0V, V0=5V, RSC=0, CI=100pF, CREF=0, IL= 1mA) ∆VO/∆T Short Circuit Current Limit ICL Reference Voltage VREF Output Noise Voltage VNO TEST CONDITION MIN.
