LP38692SD-ADJ

LP38692SD-ADJ is an adjustable low-dropout regulator (LDO). The “ADJ” suffix means you set the output voltage with an external resistor divider (Vout ≈ Vref × (1 + R1/R2) + Iadj × R1; Vref is the regulator’s internal reference). It’s used to generate a stable, user-defined supply from a higher input.
Key ideas:
- Input/output: provide a regulated Vout from a higher Vin, with typical LDO features like dropout, load regulation, and transient response.
- Adjustability: use R1 (Vout to ADJ/FB) and R2 (ADJ/FB to ground) to set Vout in the desired range.
- Protections: usually includes enable/shutdown, current-limit, and thermal shutdown; may include reverse/current protection.
- Usage notes: place input and output capacitors close to the device, observe required ESR, and follow the datasheet for pinout and package specifics (SD suffix indicates a particular package variant).
For exact electrical specs, pinout, package, and recommended application circuit, consult the LP38692SD-ADJ datasheet.

LP38692SD-ADJ is an adjustable LDO regulator. Common cross references (depends on package/specs):
- LM317/LM317T
- LM1117-ADJ (LD1117-ADJ)

Note: verify output range, dropout, current, and pinout in the datasheet before substituting, as footprints may differ.

LP38692SD-ADJ is an adjustable low-dropout regulator. Key features typically include:
- Adjustable output via external resistor network (Vout = Vref × (1 + R1/R2) + Iadj × R1; Vref ≈ 1.25 V).
- Low dropout for efficient operation.
- Enable/Shut-down input to disable output.
- Protections: overcurrent/short-circuit protection and thermal shutdown.
- Reverse-current protection to protect the regulator/load when input is removed.
- Low quiescent current suitable for battery-powered apps.
- Stable with ceramic output capacitors (requires specified ESR range).
- Wide operating temperature range (typical for automotive/battery-grade LDOs).
- Available in compact SD/ADJ package variant.
Note: refer to the exact datasheet for precise numbers (max output current, dropout, PSRR, input/output voltage ranges, and recommended capacitors).

- Pin count: 8 pins (8-pin package).
- Function: Adjustable buck (step-down) DC-DC switching regulator. Provides an adjustable output voltage via feedback (ADJ) with internal switching regulator and control circuitry.

- Manufacturer: Texas Instruments (TI). It originated with National Semiconductor; TI acquired National Semiconductor in 2011, so TI now owns the LP38692SD-ADJ.
- Company type: A multinational semiconductor company that designs, manufactures, and sells analog and digital integrated circuits and related components.

LP38692SD-ADJ is an adjustable low-dropout regulator. Common application areas:
- Portable, battery-powered devices (cell phones, wearables, cameras, handheld meters)
- Embedded systems and consumer electronics (MCUs/SoCs, FPGAs, DSPs, sensors, RF transceivers) needing an adjustable rail
- Post-regulation for analog/mixed-signal blocks (op-amps, ADC/DAC, data converters)
- USB-powered equipment and other compact electronics requiring a precise, adjustable output
- Automotive/industrial sensing and instrumentation where a stable, configurable supply is advantageous
Note: use when an adjustable, low-noise LDO is suitable for the target rail and environmental conditions.

LP38692SD-ADJ is in a 5‑pin SOT‑23 package (SC‑70‑5, SOT‑23‑5).
