It is built for supply rails that need clean, low-noise power — the 65 dB PSRR at 120 Hz knocks down line ripple before it reaches sensitive analog stages like op-amp supplies, ADC reference buffers, or VCO bias circuits. The fixed 1.5 V output means no external resistor divider; just input, output, and a couple of bypass capacitors and the rail is set. The 8-SOIC package keeps the footprint compact for space-constrained boards in industrial control, telecom infrastructure, or automotive ECU modules. ## Dropout voltage and thermal headroom Maximum dropout is 0.45 V at the full 500 mA load. The enable pin lets a system supervisor gate the output during power sequencing or fault conditions. ## Built-in protection reduces BOM count Overcurrent, overtemperature, and reverse polarity protection are integrated, so no external crowbar or thermal shutdown circuit is needed. That simplifies the BOM for a point-of-load regulator driving a mixed-signal board where a glitch on the 1.5 V rail could corrupt ADC conversions or reset a microcontroller. The fixed output also eliminates the feedback resistor pair, saving two components and one potential drift path. ## Active lifecycle — no LTB risk for new designs The LT1763CS8-1.5#PBF carries an active product status and ROHS3 compliance.","metaTitle":"LT1763CS8-1.5#PBF LDO Regulator, 1.5V Fixed, 500mA, 8-SOIC","metaDescription":"LT1763CS8-1.5#PBF from Analog Devices: positive fixed-output LDO, 1.5V at 500mA, 65dB PSRR at 120Hz, dropout 0.45V max, -40 to 125°C, 8-SOIC.
