DESCRIPTION
The J/SST270 series consists of all-purpose amplifiers for
designs requiring p-channel operation.
The TO-226AA (TO-92) plastic package provides a low-cost
option, while the TO-236 (SOT-23) package
provides surface-mount capability. Both the J and SST series
are available in tape-and-reel for automated assembly (see
Packaging Information).
