| UTC UR132 LINEAR INTEGRATED CIRCUIT 200mA LOW DROPOUT LINEAR VOLTAGE REGULATOR DESCRIPTION The UTC UR132 is a 200mA fixed output voltage low dropout linear regulator. Wide range of available output voltage fits most of applications. Built-in output current-limiting most thermal-limiting provide maximal protection against any fault conditions. 1 2 3 SOT-23 FEATURES *Guaranteed 200mA output current *Input voltage range up to 12V *Extremely tight load regulation *Fast transient response *Current-limiting and Thermal-limiting *Three-terminal adjustable or fixed voltage. 3 2 1 4 5 SOT-25 APPLICATIONS *Voltage regulator for LAN Card, CD-ROM, and DVD *Wireless communication systems SOT-23 : SOT-25 : 1: VOUT 2: GND 3: VIN 1: VIN 2: GND 3: NC 4: NC 5: VOUT PIN DESCRIPTION NAME VOUT GND VIN FUNCTION Output Ground/Adjustable Positive Power Input Function Block Diagram UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R102-007,E UTC UR132 PARAMETER LINEAR INTEGRATED CIRCUIT MIN. -0.3 -40 -65 ABSOLUTE MAXIMUM RATINGS TYP.

Note 2: Regulation is measured at constant junction temperature, using pulsed ON time. Note 3: Current Limit is measured at constant junction temperature, using pulsed ON time. Note 4: Dropout is measured at constant junction temperature, using pulsed ON time, and the criterion is VOUT inside target value2%. Note 5: Dropout test is skipped at the condition of VIN<3V. UTC UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R102-007,E UTC UR132 LINEAR INTEGRATED CIRCUIT TYPICAL APPLICATION CIRCUIT UTC UR132 APPLICATION INFORMATION A 10F (or larger) capacitor is recommended between VOUT and GND for stability. The part may oscillate without the capacitor. Any type of capacitor can be used, but not Aluminum electrolytics when operating below -25C. The capacitance may be increased without limit. A 1F capacitor (or larger) should be placed between VIN to GND.
