Gamma GM6250-4.5T92BG 300ma ultra low dropout positive voltage regulator Datasheet

GM6250
300mA ULTRA LOW DROPOUT
POSITIVE VOLTAGE REGULATOR
Description
Features
GM6250 combines high accuracy with very low
power consumption, and provides high output
current even when the application requires
extremely low input-output voltage dropout.
GM6250 includes a precision voltage reference,
an error correction circuit, over-temperature
protection, and a current limited output driver.
Fast transient response to load variations
provides excellent stability under dynamic loads.
GM6250 comes in SOT-23 (150mW), and SOT-89
(500mW).
‹
Maximum output current up 300mA
‹
Output voltage from 1.5V to 5.0V in
0.1V increments
‹
Output voltage accuracy : ±2%
‹
CMOS low power consumption,
typically 1.0µA at VOUT = 5.0V
‹
Input stability: typically 0.2%/V
‹
Ultra low dropout voltage: 0.38V @ IOUT
= 200mV at VOUT = 5.0V
‹
SOT-23 (150mW), SOT-89 (500mW) and

Application Note
Notes on Usage
1.
It is recommended to operate the GM6250 series within the stipulated absolute maximum ratings
as the IC is liable to malfunction it is operated outside the ratings.
2.
There is a possibility of heat or oscillation as a result of the impedance present between the
power supply and the IC's input. Where impedance is greater 10Ω, it is recommend to use a
capacitor (CIN) of at least 1µF at the input terminal.
3.
With a large output current, operations can be stabilized by increasing capacitor size (CIN). If CIN
is too small and capacitance of (CL) is increased, there is a possibility of oscillation due to input
impedance. In such case, operation can be stabilized by either increasing the size of CIN or
decreasing the size of CL.
4.
Please ensure the output current (IOUT) is less than Pd ÷ (VIN - VOUT) and does not exceed the
stipulated continuous for total power dissipation value (Pd) for the package.
CALCULATING POWER DISSIPATION
The GM6250 series precision linear regulators include thermal shutdown and current limit circuitry to
protect the devices. However, high power regulators normally operate at high junction temperatures so
it is important to calculate the power dissipation and junction temperatures accurately to be sure that
you use and adequate heat sink.
The thermal characteristics of an IC depend four factors:
1.
Maximum Ambient Temperature TA (℃)
2.
Power Dissipation PD (Watts)
3.
Maximum Junction Temperature TJ (℃)
4.
Thermal Resistance Junction to ambient RJA (℃/W)
These relationship of these four factors is expressed by equation : TJ = TA + PD X RJA
GM6250V2.00
Maximum ambient temperature and power dissipation are determined by the design while the
maximum junction temperature and thermal resistance depend on the manufacturer and the package
type.
