GM66102
1A LOW-DROPOUT VOLTAGE REGULATORS
Fixed and Adjustable Voltage Versions Output Current up to 1A Low Dropout Voltage 350mV @ 1A Low Ground Current Accurate 1% Guaranteed Tolerance Extremely Fast Transient Response Reverse-battery Protection "Load Dump" Protection The GM66102 series of positive fixed and adjustable regulators are designed to provide up to 1A output with high current, high accuracy and extremely low dropout voltage performance. These regulators feature 300 to 350mV (full load) dropout voltages and very low ground current. Although designed for high current loads, these devices are also useful in lower current, extremely low dropout-critical systems, where their minimal dropout voltage and ground current values are important characteristics. The GM66102's are fully protected against overcurrent, reversed input polarity (or reversed battery connection), reversed lead insertion, over-temperature operation, and transient voltage spikes (positive or negative). The GM66102's are available in TO-220, SOT-223, TO-252 and TO-263 packages.

Notes:
Note 1: Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle (1%). The maximum continuous supply voltage is 26V. Note 2: Full Load current (IFL) is defined as 1.0A for the GM66102 series. Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with VOUT + 1V applied to VIN Note 4: VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse-testing procedures to minimize temperature rise. Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus the ground pin current. Note 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
