... The RHFL4913 fixed voltage contains a PNP type power element controlled by a signal resulting from amplified comparison between the internal temperature compensated band- gap cell and the fraction of the desired output voltage value. This fractional value is obtained from an internal-to-die resistor divider bridge set by STMicroelectronics. The device is protected by several functional blocks. 5.1 Low pin count package limitations Some functions (INHIBIT, OCM, SENSE) are not available due to lack of pins ...
