It operates from a maximum 20 V input rail. PSRR spans 87 dB at 100 Hz down to 63 dB at 10 kHz — this is the band where switching-regulator ripple and line-frequency hum live, so the LDO cleans up post-regulated rails for sensitive analog loads without requiring an additional LC filter stage. Maximum dropout is 0.45 V at the full 500 mA load — the headroom between input and output must stay above 450 mV across line and load to keep the output in regulation; below that threshold the pass element enters the linear region and PSRR collapses. ## Temperature grade and protection set for industrial environments Integrated over-current, over-temperature, and short-circuit protection cover the common failure modes — a sustained output short on a 20 V rail pulls the die temperature up until the thermal-shutdown latch trips, then the part cycles back when the junction cools. Quiescent supply current is 225 µA maximum — the regulator's own draw stays below the self-discharge rate of a typical 100 mAh coin cell, making it viable for always-on sensor nodes that wake periodically to sample and transmit. ## Package and layout — the exposed pad is the thermal path The 8-SOIC with exposed pad (8-SOIC-EP) requires a thermal land on the PCB — the die attaches directly to the paddle, and the datasheet's RθJA of roughly 40-50°C/W (depending on copper area and layer count) assumes a soldered pad with vias to an internal ground plane. Enable control (active-high) lets the system processor gate the output rail during sleep — when pulled low, the LDO draws near-zero quiescent current and the output discharges through the internal pull-down. The adjustable output uses an external resistor divider from VOUT to ADJ; the internal reference is 1.224 V. The feedback pin's bias current is low enough that 10 kΩ divider resistors keep the set-point error under 1% across temperature.","metaTitle":"Renesas RAA2142504GSP#HA0 LDO, 500mA, Adjustable, 8-SOIC-EP","metaDescription":"Renesas RAA2142504GSP#HA0 20V 500mA LDO, adjustable output 1.224V to 18V, PSRR 87dB-63dB, -40°C to +125°C.
