Microchip Technology MCP1253
The MCP1253 has a switching frequency of 1 MHz and allows the use of smaller capacitors than the MCP1252, thus saving board space and cost. Both devices feature a power-good output that can be used to detect out-of-regulation conditions. The MCP1252 and MCP1253 feature thermal and short-circuit protection and are offered in space-saving, 8-lead, MSOP packages.| Part No. | MCP1253 |
