1A adjustable LDO for noise-sensitive supply rails
The TPS79601DCQ: Its PSRR profile—59 dB at 100 Hz rolling to 42 dB at 100 kHz—means it attenuates ripple from a switching pre-regulator well into the hundreds of kilohertz, making it a fit for analog supply rails where switching noise would couple into the signal chain.
Quiescent current and thermal envelope
Quiescent current is 385 µA typical—moderate for a 1 A LDO; the ground pin current does not scale with load, so the efficiency floor is set by Vdrop × Iq at light loads.
Protection and control integration
On-chip protection includes over-current, over-temperature, reverse polarity, and undervoltage lockout (UVLO), reducing the need for external supervisory ICs. The enable pin allows the regulator to be sequenced or shut down; with enable pulled low, the output goes high-impedance and quiescent current drops below 1 µA (typical). The adjustable output requires two external resistors—the feedback node is referenced to 1.2 V internal.
ROHS3 compliant, with no RoHS exemption conflicts for global shipments. The SOT-223-6 package is a standard TI footprint; the supplier device package matches the package/case (SOT-223-6).
