Product details
Overview
L78LR05DJ-TL is an onsemi 5 V voltage regulator with reset function. It is intended for board designs that need the device's confirmed function, package class, and electrical behavior in a compact production component.
For engineers reviewing L78LR05DJ-TL for datasheet, pinout, application, or equivalent information, the main selection points are component function, electrical limits, package fit, thermal behavior, lifecycle status, and whether the surrounding circuit can accept an alternate part without redesign.
Technical Context
A linear regulator is selected around input-voltage range, output voltage, load current, dropout voltage, quiescent current, noise, package dissipation, and startup behavior. Thermal headroom depends on the voltage dropped across the regulator multiplied by load current.
Low-noise or reset-equipped regulator families are often used near microcontrollers and analog circuits. The final design should check capacitor stability, enable or reset timing, transient load response, and power dissipation under maximum input voltage.
Key Specifications
| Parameter | Value | Actual Design Meaning |
|---|---|---|
| Device type | 5 V voltage regulator with reset output | Combines regulated supply generation with microcontroller reset supervision. |
| Output voltage | 5 V | Supplies standard logic and microcontroller rails. |
| Output current | 150 mA to 250 mA class depending on variant conditions | Suitable for small controller and housekeeping rails when dissipation is controlled. |
| Reset function | Power-on / power-off reset generation | Helps hold a microcontroller in reset during unstable supply conditions. |
| Package | DJ / TL legacy package and packing suffix | Use exact suffix comparison for footprint and supply format. |
Key Features
- 5 V voltage regulator with reset function
- fixed-output voltage regulation
- low-dropout operation where applicable
- compact linear regulator implementation
- microcontroller and analog supply support
- stable local power rail
- Package reference: DJ / TL legacy package and packing suffix

Applications
| Local Voltage Regulation | Portable Electronics |
|---|---|
Use Scenario: Generating a stable low-voltage rail near an IC, sensor, or analog block. Device Role: The regulator holds the output voltage within its operating range as input and load conditions change. Use Value: Local regulation improves supply cleanliness and reduces dependence on long board-level power traces. |
Use Scenario: Powering low-current circuits from a battery or intermediate rail. Device Role: The device supplies a fixed regulated output with controlled dropout and quiescent current. Use Value: Compact LDOs help reduce noise and simplify small power rails. |
| Microcontroller Supply Support | Maintenance Builds |
Use Scenario: Supplying logic circuits that need clean startup or reset coordination. Device Role: A reset-equipped regulator can coordinate supply validity with controller startup. Use Value: Defined reset behavior helps avoid brownout and unstable boot conditions. |
Use Scenario: Keeping existing assemblies aligned with their approved regulator choice. Device Role: The original regulator preserves voltage, package, and compensation assumptions. Use Value: It avoids rechecking stability and timing around a different device. |
Equivalent & Alternatives
| Alternative Type | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Same-function onsemi devices | Related onsemi 5 V voltage regulator with reset function devices can differ in ratings, package, pinout, timing, leakage, thermal resistance, or control behavior. | Useful for redesign review, but not automatically a drop-in choice for an existing PCB. | Compare the complete datasheet, footprint, electrical limits, lifecycle, and qualification requirements before substitution. |
| Cross-manufacturer equivalents | Other manufacturers may offer devices with similar headline function but different package drawings, test conditions, and reliability documentation. | Can support sourcing flexibility when the circuit allows requalification. | Use only after engineering approval of package, pin compatibility, absolute maximum ratings, and operating conditions. |
| Original L78LR05DJ-TL inventory | Maintains the original part identity and expected component behavior for boards already designed around this device. | Best suited to repair, maintenance, and controlled legacy production. | Verify traceability, date code, storage condition, packaging, and sample electrical performance. |
Quality
Quality review for L78LR05DJ-TL should confirm manufacturer traceability, suffix, package condition, date code, storage history, and packaging format. For obsolete or legacy inventory, visual inspection and sample electrical testing are especially important before production use.
Electrical validation should focus on the parameters that control the actual circuit role: voltage stress, current or drive level, leakage, switching behavior, thermal rise, and interface compatibility. The device should be evaluated in the final board environment when replacement risk is material.
Availability
L78LR05DJ-TL is available at Aetrix Electronics for prototype builds, repair, maintenance, and existing-production requirements, subject to inventory, traceability, date-code acceptance, packaging condition, and customer qualification needs.
