Automotive Low Dropout, Low Noise Post Voltage Regulator TLS205B0LD V33
Thermal model description:
THERMAL_MODEL = 1: PG-TSON-10 1s0p 600mm2 cooling area
THERMAL_MODEL = 2: PG-TSON-10 1s0p, footprint
THERMAL_MODEL = 3: PG-TSON-10 2s2p
THERMAL_MODEL = 10: No self-heating, only TEMP value used as a temperature
The TLS205B0LD V33 is a micropower, low noise, low dropout voltage regulator. The device is capable of supplying an
output current of 500 mA with a dropout voltage of 320 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 TLS205B0LD V33 is its low output noise. By adding an external 10 nF bypass capacitor output noise
values down to 24 µVRMS over a 10 Hz to 100 kHz bandwidth can be reached. The TLS205B0LD V33 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
TLS205B0LD V33 comes as fixed output voltage variant 3.3 V as well as adjustable device with a 1.22 V reference
voltage. It is available in a PG-TSON-10 Exposed Pad package.
