Features, Applications

This new very low dropout linear regulator reduces total power dissipation in the application. To achieve very low dropout, the internal pass transistor is powered separately from the control circuitry. Furthermore, with the control and power inputs tied together, this device can be used in single supply configuration and still offer a better dropout voltage than conventional PNP - NPN based LDO regulators. In this mode the dropout is determined by the minimum control voltage. The CS5253-1 is offered in a five-terminal D2PAK-5 package, which allows for the implementation of a remote-sense pin permitting very accurate regulation of output voltage directly at the load, where it counts, rather than at the regulator. This remote sensing feature virtually eliminates output voltage variations due to load changes and resistive voltage drops. Typical load regulation measured at the sense pin is less than 1.0 mV for an output voltage 2.5 V with a load step 3.0 A. The CS5253-1 has a very fast transient loop response which can be adjusted using a small capacitor on the Adjust pin. Internal protection circuitry provides for "bust-proof" operation, similar to three-terminal regulators. This circuitry, which includes overcurrent, short circuit, and over-temperature protection will self protect the regulator under all fault conditions. The CS5253-1 is ideal for generating 2.5 V supply to power graphics controllers used on VGA cards.

2. 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. 3. The VCONTROL pin current is the drive current required for the output transistor. This current will track output current with roughly a 1:100 ratio. The minimum value is equal to the quiescent current of the device.

4. This parameter is guaranteed by design and is not 100% production tested. 5. Dropout is defined as either the minimum control voltage (VCONTROL) or minimum power voltage (VPOWER) to output voltage differential required to maintain 1.0% regulation at a particular load current. 6. This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown functional test is performed on each part.


PIN 1 2 PIN SYMBOL VSENSE Adjust FUNCTION This Kelvin sense pin allows for remote sensing of the output voltage at the load for improved regulation. It is internally connected to the positive input of the voltage sensing error amplifier. This pin is connected to the low side of the internally trimmed 1.0% bandgap reference voltage and carries a bias current of about 50 mA. A resistor divider from Adjust to VOUT and from Adjust to ground sets the output voltage. Also, transient response can be improved by adding a small bypass capacitor from this pin to ground. This pin is connected to the emitter of the power pass transistor and provides a regulated voltage capable of sourcing A of current. This is the supply voltage for the regulator control circuitry. For the device to regulate, this voltage should be between 0.9 V and 1.3 V (depending on the output current) greater than the output voltage. The control pin current will be about 1.0% of the output current. This is the power input voltage. This pin is physically connected to the collector of the power pass transistor. For the device to regulate, this voltage should be between 0.1 V and 0.6 V greater than the output voltage depending on the output current. The output load current A is supplied through this pin.
