TLS115x0xx features

• 150 mA current capability

• Very high accuracy voltage tracking

• Output voltage adjustable down to 2.0 V

• Very low dropout voltage

• Very low current consumption in OFF mode

• Power good output indicates overvoltage and undervoltage

• Internally controlled so start

• Green Product (RoHS compliant)

• AEC qualified
Additional benefits of the TLS115x0xx voltage tracking regulators:

• Fast regulation

• Very good stability characteristics

• Only a small ceramic capacitor of 1 μF at the output is required

• Internal protection features make the devices robust against immediate damage:

- Output current limitation

- Short circuit protected output (to GND and to battery)

- Overtemperature shutdown

- Reverse polarity protected input

These features make the TLS115x0xx voltage tracking regulators perfectly suitable as automotive sensor supply
and as high precision supply for o-board loads.

2.2 Demoboard configuration

The jumper pins and solder pads on the demoboard provide easy to use configuration options.

Jumper connections

• EN input pin ↔ supply voltage pin VIN (JP_EN_VIN)

• ADJ pin ↔ EN pin or
ADJ pin ↔ external voltage divider
to adjust the reference voltage depending on voltage at VIN pin (JP_ADJ)

• ADJ pin ↔ RPG pin
as pull-up voltage for the power good resistor RPG (JP_PG)

Solder pads for components

• Additional input capacitor C2

• additional output capacitor C5

• Adjust capacitor C6

• Voltage divider resistor R1

• Voltage divider resistor R2

2.2.1 Jumpers

The unlabeled pin of each jumper can take an unused connector to leave the connection open.

Jumper JP_EN_VIN

The JP_EN_VIN jumper can connect the EN input pin to the supply voltage at the VIN pin.

2

The demoboard operates at an ambient temperature of 25°C.
