Its PSRR profile — 92 dB at 1 kHz rolling off to 50 dB at 100 kHz — means it attenuates switching ripple from a preceding DC-DC converter on a 5.5 V input rail down to microvolt levels for the 2.8 V load. The 180 mV maximum dropout at 150 mA sets the minimum headroom: the input must stay above 2.98 V across current and temperature to maintain regulation. ## Thermal and supply range for industrial duty The 60 µA typical quiescent current (120 µA max supply current at full load) keeps the regulator's own draw low enough for always-on 2.8 V rails in battery-powered instruments. Enable control (active-high) lets a system supervisor shut down the output to zero current, saving the quiescent draw when the rail is not needed. ## Protection and package integration Built-in over-current and over-temperature protection fold back the output under fault conditions — the regulator survives a short on the 2.8 V rail without external crowbar circuitry. ROHS3 compliant per STMicroelectronics declaration; no exemption substances reported.","metaTitle":"STMicroelectronics LDLN015PU28R LDO, 2.8V Fixed, 150mA","metaDescription":"STMicroelectronics LDLN015PU28R linear regulator: 2.8V fixed output, 150mA, 180mV dropout, 92dB PSRR at 1kHz, -40°C to 125°C.
