| UNISONIC TECHNOLOGIES CO., LTD R200LD10 VOLTAGE REGULATOR DESCRIPTION The UTC R200LD10 shows a high current, high accuracy, low-dropout voltage. The features are: low 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 * Built-in ON/OFF function, * Over current protection function, * ASO protection function * Overheat protection function * 0.3A / 3.3V(R1=2K) Output low dropout voltage regulator Lead-free: R200LD10L Halogen-free: R200LD10G ORDERING INFORMATION Normal R200LD10-TN4-R R200LD10-TN4-T R200LD10-TN5-R R200LD10-TN5-T Ordering Number Lead Free R200LD10L-TN4-R R200LD10L-TN4-T R200LD10L-TN5-R R200LD10L-TN5-T Halogen Free R200LD10G-TN4-R R200LD10G-TN4-T R200LD10G-TN5-R R200LD10G-TN5-T Package TO-252-4 TO-252-4 TO-252-5 TO-252-5 Packing Tape Reel Tube Tape Reel Tube www.unisonic.com.tw Copyright (c) 2008 Unisonic Technologies Co., Ltd 1 of 9 QW-R101-022.D R200LD10 PIN DESCRIPTIONS PIN NO. 1 2 3 4 5 PIN NAME VIN VC VOUT VADJ GND DC Input Voltage.
