TS39150

1.5A Ultra Low Dropout Fixed Positive Voltage Regulator

TO-263

Pin assignment:

1. Input

2. Ground

3. Output

Low Dropout Voltage 0.4V (typ.)

General Description

The TS39150 series are using process with a PNP pass element for high current, high accuracy and low dropout voltage regulators. These regulator s feature 400mV(typ) dropout voltages and very low ground current, these devices also find applications in lower current and low dropout critical systems, where their tiny dropout voltage and ground current values are important attributes. The TS39150 are fully protected against over current faults, reversed input polarity, reversed lead insertion, over temperature operation, and positive and negative transient voltage spikes. This series is offered in 3-pin TO-263, TO-220 package.

Specifications and test conditions see the Electrical Characteristics.

Note 2: Maximum positive supply voltage of 20V must be limited duration (<100mS) and duty cycle (<1%).

Note 4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its

nominal value measured at 1V differential.

Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the

ground pin current and output load current.

Note 6: Output current will decrease with increasing temperature, but it will be not dropped below 1.5A at the maximum
