What this LDO brings to a 3.3 V rail
The Maxim Integrated MAX8510EXK33- is a single-output, positive-voltage linear regulator delivering a fixed 3.3 V at up to 120 mA. It comes in a SC-70-5 package — roughly the footprint of a small-signal transistor — and operates over the industrial temperature range of -40°C to 85°C. The headline feature is its power-supply rejection ratio: 78 dB at 1 kHz, tapering to 54 dB at 100 kHz. That PSRR profile makes this part a natural fit for post-switcher clean-up on analog or RF rails where the upstream ripple sits in the low- to mid-frequency range.
Protection and control
On-chip over-current and over-temperature protection are included. The shutdown control pin lets a GPIO or supervisor IC pull the regulator into a low-power state. Output configuration is fixed — no external resistor divider needed, and no adjustment pin to bypass.
Sourcing and lifecycle
The MAX8510EXK33- carries an active lifecycle status — no end-of-life notice, no last-time-buy window. It remains a current-production part, suitable for new designs and ongoing production. Pricing and availability are confirmed at quote time through independent distribution; sourced to order against an RFQ.
