LP2980-N SNOS733Q – APRIL 2000 – REVISED NOVEMBER 2023 LP2980-N Micropower, 50-mA, Ultra-Low-Dropout Regulator in SOT-23 Package 1 Features VIN range (new chip): 2.5 V to 16 V VOUT range (new chip): – 1.2 V to 5.0 V (fixed, 100-mV steps) VOUT accuracy: – ±0.5% for A-grade legacy chip – ±1% for standard-grade legacy chip – ±0.5% for new chip (A grade and standard grade) Output accuracy over load, and temperature: ±1% (new chip) Output current: Up to 50 mA Low IQ (new chip): 69 μA at ILOAD = 0 mA Low IQ (new chip): 380 μA at ILOAD = 50 mA Shutdown current over temperature: – 0.01 μA (typ) for legacy chip – 1.12 μA (typ) for new chip Output current limiting and thermal protection Stable with 2.2-µF ceramic capacitors (new chip) High PSRR (new chip): – 75 dB at 1 kHz, 45 dB at 1 MHz Operating junction temperature: –40°C to +125°C Package: 5-pin SOT-23 (DBV) 2 Applications Residential breakers Solid state drives (SSD) Electricity meters Appliances Building automation 3 Description The LP2980-N is a fixed-output, wide-input, lowdropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 50 mA of load current. The LP2980-N supports an output range of 1.2 V to 5.0 V (new chip). Additionally, the LP2980-N (new chip) has a 1% output accuracy across load and temperature that can meet the needs of low-voltage microcontrollers (MCUs) and processors. In the new chip, wide bandwidth PSRR performance is 75 dB at 1 kH...
