Automotive Low Dropout Linear Voltage Regulator TLS715B0NA V50
Application Circuit

Thermal model description:
THERMAL_MODEL = 1: JEDEC 1s0p 600mm2 cooling area
THERMAL_MODEL = 2: JEDEC 1s0p 300mm2 cooling area
THERMAL_MODEL = 3: JEDEC 1s0p, footprint
THERMAL_MODEL = 4: JEDEC 2s2p, with vias
THERMAL_MODEL = 10: No self-heating, only TEMP value used as a temperature

Model performance :
- dynamic behavior not modeled (CQ/ESR stability, line/load transient response,
start-up, PSRR)
- static behavior is modelled by approximation to the real behavior of the device
over temperature
- the thermal simulations represent an approximation of the actual thermal
behavior of the device according to the JEDEC standards at power = 1 Watt
and Ambient Temperature = 85 °C

TLS715B0NA V50 - OPTIREG™ Linear Voltage Regulator is a low dropout linear voltage regulator
for load current up to 150 mA. An input voltage of up to 40 V is regulated to VQ,nom = 5 V with ±2 %
precision. The TLS715B0, with a typical quiescent current of 36 μA, is the ideal solution for systems
requiring very low operating current, such as those permanently connected to the battery.
