GM66102-1.5TB3T - Gamma Microelectronics

Description

GM66102 of positive fixed and adjustable regulators is de-

signed to provide up to 1A output with high current, high ac-

curacy, 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, and loads, these devices are also useful in

lower current, extremely low dropout-critical systems,

where their minimal dropout voltage and ground current val-

ues are important characteristics.

GM66102 is fully protected against overcurrent, reversed

input polarity (or reversed battery connection), reversed

lead insertion, over-temperature operation, and transient

voltage spikes (positive or negative). GM66102 is available

in TO-220, SOT-223, TO-252 and TO-263 packages.

APPLICATION INFORMATION

GM66102 series is high performance whit low-dropout

voltage regulators, suitable for all moderate to high-

current voltage regulator applications. Their 350mV

dropout voltage at full load makes them especially valu-

able in battery powered systems and as high efficiency

noise filters in "post-regulator" applications. Unlike

older NPN-pass transistor designs, where the minimum

dropout voltage is limited by the base-emitter voltage

drop and collector-emitter saturation voltage, dropout

performance of the PNP output of these devices is lim-

ited merely by the low V saturation voltage. A trade-

CE

off for the low dropout voltage is a varying base drive

requirement. But, Gamma's PNP process reduces this

drive requirement to merely 1% of the load current.

The GM66102 series of regulators are fully protected

from damage due to fault conditions. Current limiting is

provided. This limiting is linear and output current un-

der overload conditions is constant. Thermal shutdown

disables the device when the die temperature exceeds

the 125°C maximum safe operating temperature.

Transient protection allows device (and load) survival

even when the input voltage spikes between -20V and

+60V. When the input voltage exceeds about 35V to

40V, the overvoltage sensor temporarily disables the

regulator. The output structure of these regulators al-

lows voltages in excess of the desired output voltage to

be applied without reverse current flow. An additional

feature of this regulator family is a common pinout: a

design's current requirement may change up or down

by yet use the same board layout, as all of these regu-

lators have identical pinouts.

Thermal Design

Linear regulators are simple to use. The most com-

plicated design parameters to consider are thermal

characteristics. Thermal design requires the follow-

ing application-specific parameters:

Maximum ambient temperature, T

A

Output Current, I

OUT

Output Voltage, VOUT

Input Voltage, VIN

First, we calculate the power dissipation of the regu-

lator from these numbers and the device parameters

from this formula:

where the ground current is approximated by 1% of

I.

OUT

Then the heat sink thermal resistance is determined

with this formula:

where T 125°C and R is between 0 and

J(MAX) CS

q

2°C/W.

The heat sink may be significantly reduced in appli-

cations where the minimum input voltage is known

and is large compared with the dropout voltage. Use

a series input resistor to drop excessive voltage and

distribute the heat between this resistor and the regu-

lator, the low dropout properties of Gamma PNP reg-

ulators allow very significant reductions in regulator

power dissipation and the associated heat sink with-

out compromising performance. When this tech-

nique is employed, a capacitor of at least 0.1µF is

needed directly between the input and regulator

ground.
