GM66150-1.5TA5R

Manufacturer Part Number
GM66150-1.5TA5R
Description
1.5A ULTRA LOW-DROPOUT REGULATOR
Manufacturer
GAMMA [Gamma Microelectronics Inc.]
Datasheet
Description
The GM66150 series of positive fixed and adjustable regu-
lators is designed to provide up to 1.5A 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 GM66150 is fully protected against overcurrent, re-
versed input polarity (or reversed battery connection), re-
versed lead insertion, over-temperature operation, and tran-
sient voltage spikes (positive or negative).
Five pin fixed voltage versions feature logic level ON/OFF
control and an error flag which signals whenever the output
falls out of regulation.
On the GM66151 and GM66152, the ENABLE pin may be
tied to V if it is not required for ON/OFF control.
The GM66150 is available in 3-pin and 5-pin TO-220 and
surface mount TO-263 packages.

... But, Gamma's PNP process reduces this drive requirement to merely 1% of the load current. The GM66150 series of regulators is 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° ...

... Input and GND is recommended. This capacitor should has good characteristics to above 250kHz. Minimum Load Current The GM66150 regulators are specified between finite loads. If the output current is too small, leakage cur- rents dominate and the output voltage rises. The 5mA minimum load current swamps any expected leakage current across the operating temperature range ...
