The MAX8513/MAX8514s' first LDO controller is designed to provide a low-cost, high-current regulated output from 0.8V to 5.5V using an N-channel MOSFET or a low-current output using a low-cost NPN transistor. The MAX8513's second regulator can be used to generate 0.8V to 27V output with a low-cost PNP transistor. Both LDO regulators can operate either from the DC-DC controller output or from a higher voltage derived with a flyback overwinding on the DC-DC converter inductor. The MAX8514's second LDO regulator is designed to provide a negative output with an NPN transistor. A sequence input allows the outputs to either power up together, or for the DC-DC regulator to power up first and each LDO controller to power up in sequence. An input power-fail output ( PFO ) is provided for input power-fail warning, such as in dying-gasp applications. A power-on reset circuit with a 140ms delay is also included to indicate when all outputs have achieved regulation and stabilized. |
