NJM2828 Negative Output Low Drop Out voltage regulator GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2828 is a negative output low dropout regulator. Advanced bipolar technology achieves low noise, high precision voltage and high ripple rejection. Adjustable soft-start function is useful for reducing inrush current NJM2828F3 and controlling power-on sequence. Moreover the discharge function, the shunt SW, makes effective sequence control with the soft-start function. 1.0 F Output capacitor and small package can make NJM2828 suitable for portable items. FEATURES Low Current Consumption 0.13V (typ.) Io=60mA High Precision Output 1.5% High Ripple Rejection 65dB(typ.) f=1kHz, Vo=-7V Version Correspond to Low ESR capacitor with 1.0F ceramic capacitor. Output Current Io(max.)=100mA ON/OFF Control(Positive voltage control from 0 to +5V) Soft-start Function Shunt SW Function Thermal Shutdown Circuit Over Current Protection Bipolar Technology Package Outline SC88A PIN CONFIGURATION GND 1 5 CS V 2 IN 4 CONTROL V 3 OUT NJM2828F3-XX BLOCK DIAGRAM GND Thermal Current Protection Limit CS Bandgap Reference Output CONTROL Control V V IN OUT Ver.2016-05-10 - 1 - NJM2828 OUTPUT VOLTAGE RANK LIST Device Name V Device Name V OUT OUT NJM2828F3-14 -1.4V NJM2828F3-06 -6.0V NJM2828F3-15 -1.5V NJM2828F3-63 -6.3V NJM2828F3-02 -2.0V NJM2828F3-65 -6.5V NJM2828F3-22 -2.2V NJM2828F3-07 -7.0V NJM2828F3-03 -3.0V NJM2828F3-75 -7.5V NJM2828F3-04 -4.0V NJM2828F3-08 -8.0V NJM2828F3-05 -5.0V NJM2828F3-85 -8.5V NJM2828F3-51 -5.1V NJM2828F3-09 -9.0V NJM2828F3-55 -5.5V NJM2828F3-10 -10.0V Output voltage options available : -1.5 ~ -10.0V (0.1V step) ABSOLUTE MAXIMUM RATINGS (Ta=25C) PARAMETER SYMBOL RATINGS UNIT Input Voltage V -14 V IN Control Voltage V +5 V CONT Power Dissipation P 250(*1) mW D Operating Topr 40 +85 C Temperature Storage Temperature Tstg 40 +125 C Output Sink Current I 10 mA SINK(OFF) at OFF-state (*1): Mounted on glass epoxy board.
