Product details
Overview
L88M05TL-FA-E from onsemi is a monolithic linear low-dropout (LDO) voltage regulator IC delivering 5 V at up to 500 mA output current, with a typical dropout voltage of 0.4 V at full load. It operates from 5.8 V to 17 V input and is designed for compact, energy-efficient power supplies in audio-visual and office automation equipment using the TP3H surface-mount package.
For engineers reviewing the L88M05TL-FA-E datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at 500 mA, thermal resistance (θj-c = 20 °C/W), ripple rejection (65 dB at 100 Hz), output voltage accuracy (±3% over load/line/temp), and Pb-free TP3H package compatibility with hybrid and PCB mounting.
Technical Context
The L88M05TL-FA-E integrates an error amplifier, reference voltage source, thermal shutdown, and short-circuit protection in a single monolithic IC. Its internal start-up circuit ensures reliable turn-on, and the block diagram confirms no external pass transistor is required - the regulator uses an internal PNP-type output stage.
Stability relies on specified external capacitors: CIN = 1 μF and COUT = 100 μF (tantalum recommended), with placement adjacent to the IC mandated per test circuit guidelines. Reverse polarity (VIN negative, GND positive) causes excessive current flow and must be avoided.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5.0 V ±3% (4.85–5.15 V), stable across load, line, and temperature |
| Max output current | 500 mA continuous; peak output current up to 600 mA |
| Dropout voltage | 0.4 V typ / 0.6 V max at 500 mA - enables operation with minimal VIN–VOUT margin |
| Ripple rejection | 65 dB at 100 Hz (17 V input) - suppresses low-frequency supply noise effectively |
| Quiescent current | 0.2–0.5 mA at no load; rises to 24–50 mA at 500 mA - supports low-power standby modes |
| Thermal resistance | θj-c = 20 °C/W - allows 6.25 W dissipation with infinite heatsink at Tc = 25 °C |
| Operating temp | −20 °C to +85 °C ambient - qualified for industrial-grade AV/OA equipment environments |
Pinout & Package
The L88M05TL-FA-E is housed in the TP3H (IPAK) surface-mount package (Case 369AF), featuring three terminals: Input, Output, and Ground. The FA forming variant denotes a specific lead configuration optimized for automated assembly and thermal performance on copper-clad PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Input (VIN) | Regulator input supply node | Accepts 5.8–17 V DC; requires 1 μF bypass capacitor placed adjacent to pin |
| Output (VOUT) | Regulated 5 V power rail | Delivers up to 500 mA; requires 100 μF low-temp-coefficient capacitor (e.g., tantalum) for stability |
| Ground (GND) | Reference and return path | Common return for internal circuitry and external decoupling; reverse polarity (GND > VIN) causes destructive current flow |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 0.4 V typical at 500 mA enables use with smaller transformers and higher efficiency in 5 V systems |
| Integrated protection | Thermal shutdown and short-circuit current limiting (IOSC = 100–300 mA) prevent damage under fault conditions |
| Compact surface-mount package | TP3H footprint supports high power density and improved thermal transfer via PCB copper area (e.g., 740 mm² yields ~2.5 W Pd) |
| Stable with standard capacitors | Guaranteed stability with 1 μF ceramic input and 100 μF tantalum output - no esoteric compensation required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC78L05ACDR2G | Fixed 5 V, 100 mA output; higher dropout (1.7 V min); TO-92 package | Limited to low-current logic rails; unsuitable for 500 mA loads or space-constrained SMT designs | Select only if current demand ≤100 mA and through-hole assembly is acceptable |
| NCP1117ST50T3G | 5 V fixed, 1 A output; 1.2 V dropout; SOT-223 package; higher IQ (~6 mA) | Higher current and thermal capability but larger footprint and reduced PSRR at low frequency | Prefer when >500 mA is needed or when SOT-223 layout is already established |
Compared with MC78L05ACDR2G and NCP1117ST50T3G, the L88M05TL-FA-E uniquely balances 500 mA delivery, ultra-low 0.4 V dropout, and TP3H thermal performance - making it optimal for compact, high-efficiency 5 V rails where input headroom and board area are critical constraints.

FAQ
What is the maximum input voltage rating for the L88M05TL-FA-E?
The L88M05TL-FA-E has an absolute maximum input voltage (VINmax) of 18 V. However, its recommended operating input voltage range is 5.8 V to 17 V. Exceeding 18 V risks permanent damage, and operation above 17 V is outside specification - even briefly - due to potential thermal or electrical overstress. Always verify input transients remain within this limit in the final design.
Does the L88M05TL-FA-E require external capacitors, and what values are specified?
Yes, the L88M05TL-FA-E requires two external capacitors: CIN = 1 μF ceramic placed close to the VIN pin, and COUT = 100 μF tantalum (or low-temp-coefficient alternative) adjacent to VOUT. These values are validated in the test circuit and ensure stability across temperature and load. Using smaller or non-tantalum output capacitors may cause oscillation, especially at low temperatures.
What thermal performance can be expected from the L88M05TL-FA-E on a standard PCB?
On a glass-epoxy PCB with 740 mm² copper-clad area (18 μm thickness), the L88M05TL-FA-E achieves ~2.5 W allowable power dissipation at 25 °C ambient. With infinite heatsinking, it supports 6.25 W. Its θj-c = 20 °C/W enables effective thermal transfer to the board, but performance depends critically on copper area and solder joint quality - refer to the Pd vs. S graph in the datasheet.
Is the L88M05TL-FA-E pin-compatible with other variants in the L88M00T series?
Yes, all L88M00T series devices - including L88M05TL-FA-E, L88M05T-E, and L88M05TL-LR-E - share identical TP3H pinout (VIN, VOUT, GND) and footprint. Differences lie only in lead forming (FA vs. LR), packaging (bulk vs. tape & reel), and marking; electrical and thermal behavior is consistent across the series when operated within their respective ratings.
What protection features are integrated into the L88M05TL-FA-E?
The L88M05TL-FA-E integrates thermal shutdown and short-circuit current limiting. Thermal protection activates when junction temperature exceeds safe limits, disabling output until cooldown. Short-circuit current is limited to 100–300 mA (IOSC), preventing destructive currents during output faults. No external components are needed to enable these protections - they are fully internal and active across the full operating temperature range.
