5V 1A Low Dropout Regulator with Enable
Features
General Description
„
The G9105 positive 5V voltage regulator features the
ability to source 1A of output current. The dropout
voltage is 0.5V at 1A output current. The typical quiescent current is 5mA. Furthermore, the quiescent
current is smaller when the regulator is in the dropout
mode (VIN < 5.5V).
„
„
„
„
„
„
Dropout voltage 0.5V @ IO = 1A
Output current in excess of 1A
Output voltage accuracy ±2.5%
Quiescent current, typically 5mA
Internal short circuit current limit
Internal over temperature protection
ON/OFF control
Familiar regulator features such as over temperature and over current protection circuits are
provided to prevent it from being damaged by
abnormal operating conditions. A VEN pin is provided to disable the output when needed.

Over Temperature
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are
conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications
and test conditions see the Electrical Characteristics.
Note2: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance,
θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA /
θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. For
the TO-220F-4 package, θJA is 80°C/W (No heat sink).
Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
Note4: The type of output capacitor should be tantalum or aluminum.
Definitions
Dropout Voltage
The input/output Voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the
output drops 2% below its nominal value, dropout voltage is affected by junction temperature, load current
and minimum input supply requirements.
Load Regulation
The change in output voltage for a change in load
current at constant chip temperature. The measurement is made under conditions of low dissipation or
by using pulse techniques such that average chip
temperature is not significantly affected.
Maximum Power Dissipation
The maximum total device dissipation for which the
regulator will operate within specifications.
Line Regulation
The change in output voltage for a change in input
voltage. The measurement is made under conditions of
low dissipation or by using pulse techniques such that
average chip temperature is not significantly affected.
Quiescent Bias Current
Current which is used to operate the regulator chip
and is not delivered to the load.
