Parameters identified with boldface type apply over the full operating temperature range.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and test conditions, see the

Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.

Note 2: Unless otherwise specified VOUT = VSENSE. For the adjustable device VADJ = 0V.

Note 3: The dropout voltage for the AMS1505V is caused by either minimum control voltage or minimum power voltage. The specifications represent the

minimum input/output voltage required to maintain within 1% regulation.

Note 4: For the adjustable device the minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider

used to set the output voltage is selected to meet the minimum load current requirement.

Note 5: The control pin current is the drive current required for the output transistor. This current will track output current with a ratio of about 1:100. The

minimum value is equal to the quiescent current of the device.

PIN FUNCTIONS

Sense (Pin 1): This pin is the positive side of the

reference voltage for the device. With this pin it is

possible to Kelvin sense the output voltage at the load.

Adjust/Ground (Pin 2): This pin is the negative side of

the reference voltage for the device. Adding a small

bypass capacitor from the Adjust pin to ground improves

the transient response.

Output (Pin 3): This is the power output of the device.

VCONTROL (Pin 4): This pin is the supply pin for the

control circuitry of the device. The current flow into

this pin will be about 1% of the output current. The

voltage at this pin must be 1.3V or greater than the

output voltage for the device to regulate.

VPOWER (Pin 5): This pin is the collector to the power

device of the AMS1505V. The output load current is

supplied through this pin. The voltage at this pin must

be between 0.1V and 0.35V greater than the output

voltage for the device to regulate.
