UNISONIC TECHNOLOGIES CO., LTD M29150A/B 1.5A, VERY LOW DROP VOLTAGE REGULATORS DESCRIPTION As the UTC linear integrated LDO, the UTC M29150A/B shows a high current, high accuracy, low-dropout voltage. The features are: 400mV dropout voltage, very low ground current. Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes). LINEAR INTEGRATED CIRCUIT FEATURES * Very low dropout voltage : typ. 0.4@IOUT=1.5A * Output current guaranteed 1.5A * Fixed and adjustable output voltage * Thermal limit and Internal current * Logic controlled electronic shutdown available * Over voltage protection ORDERING INFORMATION Ordering Number Lead Free Halogen Free M29150AL-xx-TN4-R M29150AG-xx-TN4-R M29150BL-xx-TN4-R M29150BG-xx-TN4-R M29150AL-xx-TN5-R M29150AG-xx-TN5-R M29150BL-xx-TN5-R M29150BG-xx-TN5-R Package TO-252-4 TO-252-4 TO-252-5 TO-252-5 Packing Tape Reel Tape Reel Tape Reel Tape Reel www.unisonic.com.tw Copyright (c) 2009 Unisonic Technologies Co., Ltd 1 of 9 QW-R102-036.B M29150A/B MARKING INFORMATION PACKAGE VOLTAGE CODE LINEAR INTEGRATED CIRCUIT MARKING TO-252-4 TO-252-5 50 :5.0V AD :ADJ PIN CONFIGURATION PIN DESCRIPTIONS PIN NO. 1 2 3 4 5 PIN NAME INH VIN GND VOUT ADJ/NC PIN FUNCTION Inhibit Function Input Input voltage GND Output Voltage Adjustable Version Input /Not connected for fixed version UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 9 QW-R102-036.B M29150A/B BLOCK DIAGRAM Adjutable Version VIN 2 Dump Protection LINEAR INTEGRATED CIRCUIT Current Limit INH 1 Start-Up POWER 4 VOUT Thermal Protection Voltage Reference ADJ 5 + - 3 GND Fixed Version VIN 2 Dump Protection Current Limit INH 1 Start-Up POWER 4 VOUT Thermal Protection Voltage Reference NC 5 + - 3 GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 9 QW-R102-036.B M29150A/B ABSOLUTE MAXIMUM RATINGS PARAMETER DC Input Voltage DC Output Voltage Inhibit Input Voltage SYMBOL VIN VOUT VINH LINEAR INTEGRATED CIRCUIT RATINGS UNITS 30 V -0.3 ~ +20 V -0.3 ~ +20 V M29150A 14 V Over Voltage Protection OVP M29150B 35 V Output current IOUT Internally Limited mA Power Dissipation PD Internally Limited mW Junction Temperature TJ +150 C Operating Temperature TOPR -40 ~ +125 C Storage Temperature TSTG -55 ~ +150 C Notes: 1.
