This linear regulator delivers an accurate 0.5V to 1.5V output from a low-voltage power input (VIN = 1.1V to 3.6V). The MAX1510 uses a separate 3.3V bias supply to power the control circuitry and drive the internal n-channel MOSFETs. The MAX1510 provides current and thermal limits to prevent damage to the linear regulator. Additionally, the MAX1510 generates a power-good (PGOOD) signal to indicate that the output is in regulation. During startup, PGOOD remains low until the output is in regulation for 2ms (typ). The internal soft-start limits the input surge current. The MAX1510 powers the active-DDR termination bus that requires a tracking input reference. The MAX1510 can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages. The MAX1510 is available in a 10-pin 3mm x 3mm thin DFN packag...
