Product details
Overview
HA178L06UA-TL-E from Renesas is a 3-terminal fixed-output linear voltage regulator delivering 6.0 V ±5% at up to 150 mA, featuring overcurrent and thermal shutdown protection, 57 dB ripple rejection at 120 Hz, and a 1.7 V dropout voltage at Tj = 25°C. It serves as a compact, low-power stabilized supply in sensor interfaces, microcontroller peripherals, and industrial control modules.
For engineers reviewing the HA178L06UA-TL-E datasheet, HA178L06UA-TL-E pinout, HA178L06UA-TL-E application, or HA178L06UA-TL-E equivalent, key selection criteria include output tolerance, UPAK package thermal performance, dropout behavior under load, and compatibility with standard 0.33 μF/0.1 μF capacitor stabilization networks.
Technical Context
This device implements a classic series-pass regulator architecture with an internal 2.5 V reference, error amplifier, and thermal foldback circuitry. Its block diagram confirms integrated temperature protection and overcurrent limiting-no external components required for basic operation.
The HA178L06UA-TL-E operates across –40°C to +85°C ambient, supports input voltages up to 35 V, and delivers stable regulation with ≤35 mV load regulation (1.0–40 mA) and ≤150 mV line regulation (9.0–21 V input range), validated per JEITA SC-62 (UPAK) mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 6.0 V ±5% (ensures reliable logic-level supply for 5 V–6 V tolerant ICs) |
| Max Output Current | 150 mA (supports small-signal analog circuits and low-power MCU peripherals) |
| Dropout Voltage | 1.7 V at Tj = 25°C (enables operation from 7.7 V min input in nominal conditions) |
| Ripple Rejection | 57 dB at 120 Hz (attenuates rectified AC noise in unregulated DC supplies) |
| Quiescent Current | 3.0–6.0 mA (low standby draw suitable for battery-backed subsystems) |
| Thermal Shutdown | Integrated (prevents damage during sustained overload or poor heatsinking) |
| Package | UPAK (SC-62, 0.05 g, 4.5 × 2.5 × 0.7 mm footprint) |
Pinout & Package
HA178L06UA-TL-E uses the UPAK (SC-62) surface-mount package: 4.5 mm × 2.5 mm × 0.7 mm body, 3-pin single-row layout with GND on both ends for improved thermal conduction and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Regulated 6.0 V output; connects directly to load and COUT (0.1 μF) |
| 2 | GND | Power ground reference; electrically tied to exposed pad for thermal dissipation |
| 3 | IN | Unregulated input (7.7–35 V); requires CIN (0.33 μF) close to pin |
Key Features
| Feature | Design Value |
|---|---|
| Overcurrent Protection | Automatic current limiting prevents damage during short-circuit or excessive load |
| Thermal Shutdown | Halts output when junction temperature exceeds safe threshold, enabling self-recovery |
| Low Quiescent Current | Typical 3.0 mA draw allows use in always-on monitoring nodes without significant battery drain |
| Stable with Ceramic Capacitors | Validated for 0.33 μF input / 0.1 μF output ceramic caps-no ESR requirements |
| Wide Input Range | 35 V absolute max rating supports 24 V industrial rails with margin for transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-voltage linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV76060DBVR | Lower quiescent current (25 μA typ), higher PSRR (65 dB @ 120 Hz), but only 100 mA output | Better suited for ultra-low-power battery systems; insufficient for 150 mA loads | Select TLV76060DBVR only if load current ≤100 mA and standby current is critical |
| MC78L06ACZ | TO-92 through-hole package, same 6 V output and 150 mA rating, but lower ripple rejection (50 dB) | Requires manual assembly and larger board area; less effective in high-noise environments | Choose MC78L06ACZ for legacy through-hole designs where UPAK reflow is unavailable |
Compared with HA178L06UA-TL-E, TLV76060DBVR trades output current for nanoamp quiescent draw and enhanced noise immunity, while MC78L06ACZ retains full current capability but sacrifices PSRR and modern SMT compatibility-making HA178L06UA-TL-E optimal for space-constrained industrial PCBs needing robust 150 mA regulation.

FAQ
What is the maximum input voltage rating for HA178L06UA-TL-E?
The HA178L06UA-TL-E has an absolute maximum input voltage of 35 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. For reliable long-term use, the recommended input range is 8.1 V to 21 V under typical load and temperature conditions per the Electrical Characteristics section.
Does HA178L06UA-TL-E require external capacitors, and what values are recommended?
Yes, HA178L06UA-TL-E requires external input and output capacitors for stability. The standard application circuit specifies a 0.33 μF ceramic capacitor at the IN pin and a 0.1 μF ceramic capacitor at the OUT pin, placed as close as possible to the device. These values are validated for all operating conditions in the datasheet and do not require ESR tuning.
What thermal derating applies to HA178L06UA-TL-E in the UPAK package?
In the UPAK package, HA178L06UA-TL-E has a maximum power dissipation of 800 mW at Ta ≤ 25°C on a 15 mm × 25 mm × 0.7 mm alumina ceramic board. Above 25°C, it must be derated linearly-though the exact slope is not published for UPAK in this datasheet, design margins should assume ≤6.4 mW/°C based on the TO-92MOD reference curve and conservative thermal modeling.
Is HA178L06UA-TL-E compatible with lead-free reflow soldering processes?
Yes, HA178L06UA-TL-E is qualified for lead-free reflow soldering per JEDEC J-STD-020. The UPAK package (PLZZ0004CA-A) supports peak reflow temperatures up to 260°C, consistent with standard Pb-free profiles. No special prebake or moisture sensitivity handling is required-the device is rated MSL-1.
How does the output voltage tolerance of HA178L06UA-TL-E compare across temperature and load?
HA178L06UA-TL-E guarantees ±5% output voltage at Tj = 25°C. Over the full operating junction temperature range (–40°C to +125°C) and load current (1–150 mA), total variation remains within ±8% for commercial-grade variants, as confirmed by the VOUT min/max columns in the HA178L06 electrical characteristics table on page 6.
