8682l Ic Datasheet [best] May 2026

Technical Deep Dive: The 8682L Low Dropout Voltage Regulator

In the crowded field of power management ICs (PMICs), the 8682L has established itself as a reliable workhorse for applications requiring stable, low-noise voltage rails. While often overshadowed by more complex switching converters, this LDO (Low Dropout Regulator) offers a compelling balance of simplicity, thermal efficiency, and output purity.

How to Set the Charge Current (Rprog Calculation)

The most critical design parameter for the 8682L is the programming resistor connected between PROG (pin 6) and GND. The formula is:

[ I_CHG = \fracV_PROG \times 1000R_PROG ]

Where ( V_PROG ) is typically 1.0V during constant-current charging.

Thus:

• For 100mA charge current: ( R_PROG = 1.0V / 100mA \times 1000 = 10k\Omega )
• For 500mA charge current: ( R_PROG = 2k\Omega ) (standard USB charging)
• For 800mA charge current: ( R_PROG = 1.25k\Omega ) (use 1.2k or 1.3k)

Important: The 8682L does not support currents above 800mA reliably in SOT-23-6 package due to thermal limitations. For higher currents, choose a different IC.

Why the 8682L Datasheet Matters

Without the official datasheet, using the 8682L in a design is risky. Key parameters that are only found in the datasheet include:

1. Absolute Maximum Ratings – Exceeding input voltage or current can destroy the IC.
2. Pin Configuration – Misconnecting ground, input, output, or enable pins leads to malfunction.
3. Thermal Data – Junction-to-ambient resistance (θJA) determines if you need a heatsink.
4. Typical Application Circuit – The recommended capacitor values, inductor selection (if switching regulator), and PCB layout.
5. Electrical Characteristics – Line regulation, load regulation, dropout voltage, quiescent current, and ripple rejection.

Deep Review Approach

• Specifications Analysis: Compare the IC's specifications with the requirements of your project. This includes power consumption, operating frequency, and interface types.

• Application Notes: Look for application notes provided by the manufacturer. These offer insights into best practices for design, layout, and software interaction. 8682l ic datasheet

• Manufacturer Support: Evaluate the level of support provided by the manufacturer, including availability of development tools, software libraries, and documentation.

• Cross-Reference and Alternatives: Sometimes, specific ICs can be hard to source. Look for cross-reference information to find alternative parts.

• Manufacturer Reputation and Quality: Consider the manufacturer's reputation for reliability, quality, and support.
