DESCRIPTION

The DCMAR05 series of DC/DC switching regulators offers 0.5A output current in a

compact 0.45” x 0.30” x 0.40” standard SIP-3 package. This series consists of fully

regulated single output models with high efficiency and low ripple & noise. Each

model in this series has short circuit and over temperature protection, no minimum

load requirement, and is RoHS & REACH compliant. Please contact factory for

order details.

Size: 0.45in x 0.30in x 0.40in (11.5mm x 7.55mm x 10.2mm)
