RH117 Positive Adjustable Regulator W W U W U DESCRIPTIO ABSOLUTE The RH117 is a 3-terminal positive adjustable regulator capable of supplying up to 0.5A (H package) or 1.5A (K package). The output is adjusted using two external resistors for a range of 1.2V to 37V. The devices have full current limit thermal overload safe area protection, all of which remain functional even if the adjustment terminal is disconnected.

Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Note 3: Guaranteed by design, characterization or correlation to other tested parameters. Note 4: TJ = 25∞C unless otherwise noted. Note 1: Unless otherwise specified, these specifications apply for VIN – VOUT = 5V; and IOUT = 0.1A for the H package (TO-39) and IOUT = 0.5A for the K package (TO-3) package. Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the TO-39 and 20W for the TO-3. IMAX is 0.5A for the TO-39 and 1.5A for the TO-3.
