Dual-rail LDO with 80 dB PSRR floor
The TLV7111812DSER from Texas Instruments is a dual-output low-dropout regulator delivering 200 mA per channel from fixed 1.8 V and 1.2 V rails. The 80 dB PSRR at 10 Hz drops to 50 dB at 100 kHz — this keeps ripple from upstream switching converters out of sensitive analog supply domains across the audio band and into the lower switching frequencies.
Thermal and load protection for always-on rails
The 110 µA quiescent current per channel suits battery-powered always-on rails where every microamp counts. Protection features include overcurrent, overtemperature, short-circuit, and under-voltage lockout (UVLO) — the regulator shuts itself down before the load or the die sees damage.
Housed in a 6-WSON (1.5x1.5 mm) package, the TLV7111812DSER occupies minimal PCB area. The supplier device package is 6-WSON (1.5x1.5) — the exposed thermal pad under the package conducts heat to the board copper.
ROHS3 compliant per the manufacturer's declaration.
