Automotive Low Dropout, Low Noise Post Voltage Regulator TLS203B0EJ V50
Thermal model description:
THERMAL_MODEL = 1: DS08 1s0p 600mm2 cooling area
THERMAL_MODEL = 2: DS08 1s0p, footprint
THERMAL_MODEL = 3: DS08 2s2p
THERMAL_MODEL = 10: No self-heating, only TEMP value used as a temperature
The TLS203B0EJ V50 is a micropower, low noise, low dropout voltage 5 V regulator. The device is capable of
supplying an output current of 300 mA with a dropout voltage of 290 mV. Designed for use in battery-powered
systems, the low quiescent current of 30 µA makes it an ideal choice.
A key feature of the TLS203B0EJ V50 is its low output noise. By adding an external 10 nF bypass capacitor output
noise values down to 42 µVRMS over a 10 Hz to 100 kHz bandwidth can be reached. The TLS203B0EJ V50 voltage
regulator is stable with output capacitors as small as 3.3 µF. Small ceramic capacitors can be used without the
series resistance required by many other linear voltage regulators.
Internal protection circuitry includes reverse battery protection, current limiting and reverse current protection. The
TLS203B0EJ V50 comes as 5.0 V fixed output voltage variant and is available in a PG-DSO-8 Exposed Pad.
