The TCR5AM series achieves an ultra-low dropout voltage by adopting a secondary bias voltage supply (VBAT) as a reference voltage. Applying VBAT=3.3V enables a 0.6V output voltage operation with typical dropout voltages as low as 0.090V (at IOUT=300mA) and 0.150V (at IOUT=500mA). This performance makes the TCR5AM series suitable for high-current loads (such as RF or camera circuits) in battery operated designs.
In addition to the excellent drop-out performance the TCR5AM series includes integrated protection features like over-current and over-temperature protection as well as under-voltage lock-out and auto output discharge functions.
The TCR5AM comes in the ultra-small DFN5B package (1.2×1.2×0.38mm) with 600mW power dissipation. As the LDO can be mounted with small ceramic input and output capacitors it is the perfect solution for high-density board assemblies.
