RH117 Positive Adjustable Regulator
DESCRIPTIO
ABSOLUTE
AXI U
RATI GS
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. The wafer lots are processed to LTC's in-house Class S flow to yield circuits usable in stringent military applications. In addition to 883 processing, the RH117 is subjected to 100% burn-in in thermal limit.

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.
Note 2: Regulation is measured at a constant junction temperature using pulse testing with a low duty cycle. 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 = 25C unless otherwise noted.

TABLE 2: ELECTRICAL TEST REQUIRE E TS
MIL-STD-883 TEST REQUIREMENTS Final Electrical Test Requirements (Method 5004) Group A Test Requirements (Method 5005) Group C and D End Point Electrical Parameters (Method 5005) * PDA Applies to subgroup 1. See PDA Test Notes. SUBGROUP 1*,2,3 1,2,3 1 PDA Test Notes The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-883 Class B. The verified failures of group A, subgroup 1, after burn-in divided by the total number of devices submitted for burnin in that lot shall be used to determine the percent for the lot. Linear Technology Corporation reserves the right to test to tighter limits than those given.
