This is a space-saving alternative to two separate LDOs when a bipolar supply is needed for analog front-ends, op-amp rails, or ADC/DAC reference paths. ## PSRR and dropout — what they mean for the supply rail PSRR is 68 dB at 120 Hz, dropping to 54 dB at 120 Hz — the higher figure is typical for the positive regulator, the lower for the negative side. At 68 dB, a 100 mVpp ripple on the input at 120 Hz (full-wave rectified mains) is attenuated to roughly 40 µVpp on the output, which is clean enough for a 16-bit ADC reference without additional post-filtering. Dropout voltage is 0.27 V typ (0.3 V max) at 150 mA — the input rail must stay at least 300 mV above the ±5V output across the full load range to maintain regulation. For a 5V output, a 5.5V input rail provides comfortable headroom; a 5.0V rail would drop out under load. ## Industrial temperature range and protection suite The 125°C ceiling gives margin for self-heating in a compact 14-DFN package. Built-in protection includes over-current limiting, thermal shutdown, and reverse-polarity protection — the reverse-polarity clamp prevents damage if the input supply is accidentally reversed during bench testing or field wiring. ## Active lifecycle and compliance documentation It is RoHS3 compliant (lead-free) with no exemptions.","metaTitle":"LT3032IDE-5#PBF Dual ±5V LDO, 150mA, 14-DFN","metaDescription":"Active Analog Devices LT3032IDE-5#PBF dual ±5V LDO, 150mA per channel, 68dB PSRR at 120Hz, -40°C to 125°C.
