LM1108SF overview
LM1108SF is a component documented by HTC Korea TAEJIN Techno. The PDF description identifies it as "300mA C-MOS L.D.O. Regulator." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Regulator LM1108F/SF Extremely Low Supply Current(50µA,Typ.) Very Low Dropout Voltage 300mA Output Current High Output Voltage Accuracy +/- 1.4 % Standardor Custom Output Voltages Over Currentand Over Temperature Protection Small input/out.
- Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators).
- LM1108 key features include ultra low noise operation, very low dropout voltage (typically 240mV at full load), and fast response to step changes in load.
- The LM1108 is stable with an output capacitor of only1µF and has a maximum out put current of 300mA.
- It is available in a SOT-23 & SOT-89 package SOT-23-5L (SOT-25) SOT-89 SOT-23 300mA C-MOS L.D.O.
- HTC ABSOLUTE MAXIMUM RATING (Note 1) Supply Voltage (Vin) +6.5V Output Current (Iout) 300 mA Output Voltage (Vout) Vss-0.3 to Vin+0.3V Total Power Dissipation (Pd) SOT-89 500 mW SOT-23 230 mW Operating Ambient Temperature (Topr) -30 ~ +80.
- In addition,VOUT remains stable and with in regulation over theen tire 0mA to IOUT MAX operating load currentrange, (an important consideration in RTC and CMOS RAM battery back-up applications).

Engineering review checklist
- Verify capacitance tolerance, rated voltage, temperature range and any DC-bias derating.
- Check ESR, ripple-current capability, lifetime and polarity requirements under worst-case conditions.
- Confirm package dimensions, land pattern and reflow or mounting limits for the selected ordering code.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
