Detail Description

The AP6265 is a CMOS low-dropout linear regulator. The device provides preset 1.8V, 2.5V and 3.3V output voltages for output current up to

1.5A. As illustrated in function block diagram, it consists of a 0.95V bandgap reference, an error amplifier, a P-channel pass transistor and an internal feedback voltage divider.

The bandgap reference voltage is connected to the error amplifier, which compares this reference with the feedback voltage and amplifies the voltage difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled lower, which allows more current to pass to the output pin and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled up to decrease the output voltage.

The output voltage is feed back through an internal resistive divider connected to OUT pin. Additional blocks include an output current limiter, thermal sensor, and shutdown logic.

Internal P-channel Pass Transistor

The AP6265 features a P-channel MOSFET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive, which reduces quiescent current. PNP-bas- ed regulators also waste considerable current in dropout when the pass transistor saturates, and use high base-drive currents under large loads.

The AP6265 does not suffer from these problems and consumes only 60μA (Typ.) of current consum- ption under heavy loads as well as in dropout conditions.

Output Voltage Selection

For voltage type of AP6265, the output voltage is preset at an internally trimmed voltage. The first two digits of part number suffix identify the output voltage (see Ordering Information). For example, the AP6265-33 has a preset 3.3V output voltage.

Current Limit

The AP6265 also includes a fold back current limiter. It monitors and controls the pass transis- tor’s gate voltage, estimates the output current, and limits the output current within 2.0A (Typ.).

Thermal Overload Protection

Thermal overload protection limits total power dissipation in the AP6265. When the junction temperature exceeds T

J

= +155°C, a thermal sensor turns off the pass transistor, allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the junction temperature cools down by 20°C, resulting in a pulsed output during continuous thermal overload conditions.

Thermal overload protection is designed to protect the AP6265 in the event of fault conditions. For continuous operation, the absolute maximum oper- ating junction temperature rating of T should not be exceeded.

J

= +125°C

Operating Region and Power Dissipation

Maximum power dissipation of the AP6265 depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The power dissipation across the devices is

P = I

x (V

). The resulting maximum power dissipation is:

Where (T

CA

is the thermal resistance through the printed circuit board, copper traces and other materials to the surrounding air. For better heat-sinking, the copper area should be equally shared between the IN, OUT, and GND pins.

Dropout Voltage

A regulator’s minimum input-output voltage differential, or dropout voltage, determines the lowest usable supply voltage. In battery-powered systems, this will determine the useful end-of-life battery voltage. The AP6265 use a P-channel

MOSFET pass transistor, its dropout voltage is a function of drain-to-source on-resistance R

DS(ON) multiplied by the load current.
