The R-5XXX series is a high performance 1.2V to 5.0V , 2Amp to 5Amp,12-Pin SIP (single in-line package)

integrated switching regulator (ISR). Synchronuous - rectified design yields excellent efficiencies up to 96%.

Short circuit protection with crowbar function to reduce the short circuit input current to under 50mA. Autosense

function compensates for any losses in long circuit loops.

... Package Weight Packing Quantity MTBF (Nominal Vout, 100% load) 1. Requires an electrolytic or tantalum output capacitor for proper operation in all applications (the capacitor to be placed as close as possible to the output pins) Notes: 100µF for R-52xxPA/DA, R-53xxPA/DA and R-54xxPA/DA or 220µF for R-55xxPA/DA OFF pin driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET. ...

... The R-52xx, R-53xx, R-54xx series can be used in parallel to upgrade the output current capacity for the same output voltage. For example, the R-543.3PA can parallel up with another R-554.3PA to give amps or with the R-533.3PA or R-523.3PA types to give output currents Amps or 6 Amps. The R-55xx series cannot be paralleled. ...
