L1183A 数据手册
UNISONIC TECHNOLOGIES CO., LTD L1183A 300mA CMOS LDO DESCRIPTION The UTC L1183A is a COMS positive linear regulator. One of it’s feature is the very low quiescent current typical as low as 30μA and its dropout voltage is extremely low with 300mA output current. The internal circuit includes thermal shutdown and current fold-back to prevent device failure when the circuit is operated in the bad conditions. In application, the UTC L1183A needs a low noise, regulated supply. For stable operation, the output capacitance value should be 2.2μF or more. The UTC L1183A is an ideal for battery applications, such as instrumentations, portable electronics, wireless devices, cordless phones, PC peripherals, and battery powered widgets. Preliminary CMOS IC FEATURES * Accurate To Within 1.5% * Quiescent Current: 30μA * Internal Over-Temperature Shutdown * With Current Limiting * Internal Short Circuit Current Fold-Back * Has Power-Saving Shutdown Mode * Very Low Temperature Coefficient * Halogen Free ORDERING INFORMATION Ordering Number L1183AG-xx-AF5-R L1183AG-xx-AG6-R Package SOT-25 SOT-26 Packing Tape Reel Tape Reel Note: xx: Output Voltage, refer to Marking Information. www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-315.e L1183A MARKING INFORMATION PACKAGE VOLTAGE CODE Preliminary CMOS IC MARKING 3 2 1 SOT-25 12 :1.2V 15 :1.5V 28 :2.8V 31 :3.1V 33 :3.3V Voltage Code SXXAG 4 5 SOT-26 PIN CONFIGURATION VIN 1 GND 2 EN 3 5 VOUT 4 NC SOT-25 SOT-26 PIN DESCRIPTION PACKAGE PIN NO. 1 2 SOP-25 3 4 5 1 2 SOP-26 3 4 5 6 PIN NAME VIN GND EN NC VOUT SENSE GND BYP EN VDD VOUT Output voltage pin.
