The MAX38913/MAX38914 is a low-noise linear regulator that delivers up to 1A of load current with as low as 4μVRMSof output noise. The MAX38913/MAX38914 can dynamically change its output voltage between two separate levels. The MAX38913/MAX38914 has the pass-through mode which, when enabled, completely bypasses the linear regulator.This regulator maintains ±1% output accuracy over a wide input voltage range, temperature, and load conditions. The no-load quiescent current in the regulation mode is 1.37mA. During the pass-through mode, unlike the conventional dropout mode of an LDO, the MAX38913/MAX38914 consumes very little quiescent current. The MAX38913/MAX38914 has a 6Ω active discharge feature to quickly discharge output capacitors of up to 300μF.The MAX38913 has 33 programmable output-voltage settings for both voltage selections. The MAX38914 has pre-programmed output voltage levels of 2.3V and 2V. The MAX38913/MAX38914 is packaged in either a space-saving 12-bump WLP or a full-featured 3mm x 3mm, 14-pin TDFN package. Optional power-OK and power-on-reset pins are available in the 14-pin TDFN version.ApplicationsImage SensorsPortable Sensor ApplicationsSD Memory Cards

The MAX391/MAX392/MAX393 are precision, quad, single-pole/single-throw (SPST) analog switches designed to operate at +3V, +5V, or ±5V. The MAX391 has four normally closed (NC) switches, and the MAX392 has four normally open (NO) switches. The MAX393 has two NO and two NC switches. All three devices offer low leakage (100pA max) and fast switching speeds (tON≤ 130ns, tOFF≤ 75ns). Power consumption is just 1µW—ideal for battery-operated equipment. All devices operate from a single +3V to +15V supply or from dual ±3.0V to ±8V supplies.With ±5V supplies, the MAX391/MAX392/MAX393 offer guaranteed 2Ω max channel-to-channel matching, 30Ω max on-resistance (RON), and 4Ω max RONflatness over the specified range.These switches are also fully specified for single +5V operation, with 2Ω max RONmatch, 60Ω max RON, and 6Ω max flatness.These low-voltage switches also offer 5pC max charge injection, and ESD protection is greater than 2000V, per method 3015.7.Applications±5V DACs and ADCsAudio and Video SwitchingBattery-Powered ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXSample-and-Hold CircuitsTest Equipment
