NJM12884 LDO with Reverse Current Protection / Soft Start / Discharge Function GENERAL DESCRIPTION The NJM12884 is a low dropout regulator which achieves high ripple rejection, low noise and high speed response with the bipolar technology. Adjustable soft-start function is useful for reducing inrush current and controlling power-on sequence. Moreover the discharge function makes effective sequence control with the soft-start function. In addition, the reverse current protection makes external SBD unnecessary. ■ PACKAGE OUTLINE NJM12884U2 NJM12884DL3 FEATURE Operating Voltage Range 2.3V to 6.5V Output Voltage Accuracy VO 1.0% Output Current IO(min.)=500mA Reverse Current Protection Adjustable soft-start Function Discharge Function ON/OFF Control Correspond to Low ESR capacitor (MLCC) Thermal Shutdown Circuit Over Current Protection Circuit Package Outline SOT-89-5, TO-252-5 PIN CONFIGRATION VOUT 1 5 VIN GND 2 2 GND CS 3 3 4 CONTROL 5 CS 4 VOUT 3 GND 2 VIN CONTROL 1 NJM12884DL3 NJM12884U2 BLOCK DIAGRAM VIN CONTROL VOUT Reverse Current Protection Thermal Protection CS Bandgap Reference Over Current Protection GND Ver.2015-07-28 -1- NJM12884 OUTPUT VOLTAGE RANK LIST SOT-89-5 TO-252-5 Output Device Name Device Name Voltage NJM12884U2-15 1.5V NJM12884DL3-15 NJM12884U2-18 1.8V NJM12884DL3-18 NJM12884U2-25 2.5V NJM12884DL3-25 NJM12884U2-33 3.3V NJM12884DL3-33 NJM12884U2-05 5.0V NJM12884DL3-05 ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL Input Voltage VIN Control Pin Voltage VCONT Output Voltage VOUT Soft start Pin Voltage VCS Power Dissipation PD Junction Temperature Range Operating Temperature Range Storage Temperature Range Tj Topr Tstg Output Voltage 1.5V 1.8V 2.5V 3.3V 5.0V (Ta=25 C) MAXIMUM RATING UNIT -0.3 ~ +7 -0.3 ~ +7 -0.3 ~ +5.5 Vo 1.8V -0.3 ~ +7 Vo 1.8V -0.3 ~ +4 625(*1) SOT-89-5 2400(*2) 1190(*1) TO-252-5 3125(*2) -40 +150 -40 +125 -50 +150 V V V V V mW C C C 2 (*1): Mounted on glass epoxy board.
