The MIC37122 are high-performance, low-noise, low dropout regulators. Each of these LDOs is capable of sourcing 1A output current, offers high power supply rejection, and low output noise. These general purpose LDOs are most suitable for consumer applications such as multimedia devices, set-top boxes, Blu-ray players, handheld devices, and gaming consoles. The MIC37112 and MIC37122 feature adjustable output voltages while the MIC37110 and MIC37120 come in fixed 1.8V output voltage options. All devices feature 2% initial output voltage accuracy, typical dropout of 230mV at 1A, and low ground current. This family of low-noise regulators is available in 2mm x 2mm Thin MLF®, SOIC-8, and SOT-223 packages and they all have an operating junction temperature range of -40°C to +125°C.Input voltage range: 2.375V to 5.5V Output voltage adjustable down to 1.0V (MIC37122) Stable with small, 2.2µF ceramic output capacitor 230mV typical dropout at 1A 1A minimum guaranteed output current ±2.0% initial accuracy Low ground current High PSRR: >60dB, up to 1kHz Output auto-discharge circuit (MIC37122) Thermal shutdown and current limit protection
