GM6603-1.5TA3R

Manufacturer Part Number
GM6603-1.5TA3R
Description
3.0A LOW DROPOUT PRECISION LINEAR REGULATORS
Manufacturer
GAMMA [Gamma Microelectronics Inc.]
Datasheet
Description
GM6603 of positive adjustable and fixed regulators are de-
signed to provide 3.0A output with low dropout voltage per-
formance.
On-chip trimming adjusts the reference voltage to 2.0%. To
work in post regulators or microprocessor power supplies
where low voltage operation and fast transient response
are required.
Device includes over-current protection and thermal shut-
down protection as well.
Pin-to-pin compatible with LT1085 family of regulators,
GM6603 is available in TO-252, TO-220, and surface-
mount TO-263 packages.

... ADJ R2 In GM6603 linear regulators, the discharge path is through a large junction, and protection diodes are normally not needed. However, if the regulator is used with large output capacitance values and the in- put voltage is instantaneously shorted to ground, damage can occur. In this case, a diode connected as shown above in Figure 1 ...

... Output Voltage Sensing GM6603 series is three terminal regulator, so they can- not provide true remote load sensing. Load regulation is limited by the resistance of the conductors connect- ing the regulator to the load. For best results, GM6603 should be connected as shown in Figure OUT GM6603-3 ...
