I

Input.

The device is supplied by the input pin I. A capacitor at the input pin is

required if the device is more than 6 inches away from the main input filter

TLS203B0 is designed to withstand reverse voltages on the input pin I with

respect to GND and output Q. In the case of reverse input (e.g. due to a wrongly

attached battery) the device will act as if there is a diode in series with its input. In

this way there will be no reverse current flowing into the regulator and no reverse

voltage will appear at the load. Hence, the device will protect both - the device

itself and the load.

Exposed Pad.

To ensure proper thermal performance, solder Pin 11 of TSON-10

to the PCB ground and tie directly to Pin 6. In the case of DSO-8 EP as well solder

Pin 9 to the PCB ground and tie directly to Pin 6 (GND).

1) A maximum value of 10 nF can be used for reducing output voltage noise over the bandwidth from 10 Hz to 100 kHz.

2) Normally several microamperes.

3) Typical value is 1 µA.

4) In general the output impedance of a battery rises with frequency, so it is advisable to include a bypass capacitor in battery-

powered circuits. Depending on actual conditions an input capacitor in the range of 1 to 10 µF is sufficient.
