3 / 4 page  3.5 - 19 3.5 OM1324NTM, OM1324STM, OM1324NKM, OM1324SMM, OM1324NMM, OM1324N2M OM1324STM Vin Cin* 0.1 µF Vout R2 Adjust IAdj R1 240Ω APPLICATION *Cin is required if regulator is located an appreciable distance from power supply filter. ** Co is not needed for stability, however it does improve transient response. Vout = 1.25 V (1 + )+ IAd j R2 Since IAdj is controlled to less than 100 µA, the error associated with this term is negligible in most applications. R2 R1 Parameter Symbol Test Conditions Min. Max.

Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used. Changes in output voltage due to heating effects must be taken into account separately. 2. If not tested, shall be guaranteed to the specified limits. 3. The • denotes the specifications which apply over the full operating temperature range. ELECTRICAL CHARACTERISTICS -55°C ≤ T A ≤ 125°C, IL = 8mA (unless otherwise specified) OM1324N2M |
