Product details
Overview
UPC29S10GR-E2-A from Renesas Electronics is a 10 V, 100 mA low-dropout linear voltage regulator with active-high ON/OFF control, ±2% output voltage accuracy at 25°C, dropout voltage of 0.4–1.0 V at 100 mA, and integrated thermal shutdown, overcurrent, and saturation protection. It is designed for flash memory programming in single-chip microcomputers.
For engineers reviewing the UPC29S10GR-E2-A datasheet, UPC29S10GR-E2-A pinout, UPC29S10GR-E2-A application, or UPC29S10GR-E2-A equivalent, this page delivers verified electrical specs, SOP-8 package details, functional role in power sequencing, and validated alternative options for embedded microcontroller supply rails.
Technical Context
The UPC29S10GR-E2-A implements a standard LDO architecture with internal reference voltage, error amplifier, drive transistor, and protection circuitry including thermal shutdown (trips at TJ = 150°C), overcurrent limiting (180 mA short-circuit current), and saturation protection. Its ON/OFF control enables system-level power gating.
It operates across −30°C to +85°C ambient temperature, supports input voltages from 11 V to 18 V, and maintains stable regulation under load currents up to 100 mA with ≤100 mV load regulation and ≥40 dB ripple rejection at 120 Hz. Startup quiescent current is 10–20 mA at VIN = 9.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.00 V ±2% (min 9.80 V, max 10.10 V at TJ = 25°C); ensures precise biasing for flash memory write/erase cycles. |
| Max Output Current | 100 mA continuous; sufficient for on-chip flash programming current in NEC/Renesas μCOM microcontrollers. |
| Dropout Voltage | 0.4–1.0 V at 100 mA; enables operation with minimal headroom-e.g., 11 V input sustains 10 V output. |
| ON/OFF Logic | Active-high control (VON/OFF1 = 1.8–2.0 V threshold); interfaces directly with CMOS logic without level-shifting. |
| Quiescent Current | 3.3–5.0 mA (IO = 0 mA); low static draw preserves system standby efficiency. |
| Thermal Shutdown | Triggers at TJ ≥ 150°C; prevents permanent damage during sustained overload or poor PCB heat sinking. |
| Ripple Rejection | 40–48 dB at 120 Hz; suppresses line-frequency noise from upstream unregulated supplies. |
Pinout & Package
UPC29S10GR-E2-A is housed in an 8-pin plastic SOP package (5.72 mm × 7.8 mm, 225 mil width), compliant with JEDEC MS-012, with 1.27 mm lead pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Regulator input supply | Accepts 11–18 V DC; requires 0.1–0.47 µF bypass capacitor close to pin to prevent oscillation. |
| 2 (NC) | No connect | Internally unused; must remain unconnected per datasheet to avoid parametric shift or instability. |
| 3 (ON/OFF) | Enable control input | Active-high digital input; drives output to regulated state when ≥1.8 V; pulls to GND for full shutdown (IBIASOFF = 10 µA). |
| 4 (NC) | No connect | Internally unused; must remain unconnected. |
| 5 (GND) | Ground reference | Primary return path for load current and internal bias; must be low-impedance and tied to system ground plane. |
| 6 (NC) | No connect | Internally unused; must remain unconnected. |
| 7 (OUTPUT) | Regulated output | Delivers stable 10 V to load; requires ≥10 µF output capacitor (low-ESR) for transient stability and ripple suppression. |
| 8 (NC) | No connect | Internally unused; must remain unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| ON/OFF function | Active-high enable with 0.8–2.0 V logic thresholds; allows direct interface with microcontroller GPIO for power sequencing. |
| High-accuracy output | ±2% tolerance at 25°C (9.80–10.10 V); meets tight voltage requirements for flash memory VPP programming. |
| Integrated protection | Thermal shutdown, overcurrent limit (180 mA), and saturation protection eliminate need for external fault-handling circuitry. |
| Low-noise regulation | 210 µVr.m.s. output noise (10 Hz–100 kHz); minimizes interference in sensitive analog/mixed-signal subsystems. |
| SOP-8 surface-mount | Standard 5.72 mm × 7.8 mm footprint; compatible with automated reflow (peak 235°C) and wave soldering processes. |
Applications
| Flash Memory Programming Supply | Microcontroller Core Power Rail |
|---|---|
|

IC Role / Device Role / Timing Role: Low-dropout post-regulator isolating sensitive analog blocks from noisy digital supply domains. Use Value: Reduces power supply-induced measurement error by suppressing ripple and load transients. |
| Industrial Sensor Interface Power | Legacy System Voltage Translation |
|

IC Role / Device Role / Timing Role: Stable, protected voltage source maintaining sensor bridge accuracy across temperature and load variation. Use Value: Eliminates calibration drift caused by supply variation-output voltage drift <0.5 mV/°C. |
Use Scenario: Replacing obsolete 10 V regulators in legacy equipment where input is 12–15 V and board space is constrained. IC Role / Device Role / Timing Role: Pin-compatible drop-in upgrade offering improved dropout, tighter tolerance, and built-in protection vs. older discrete designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-10CPK | Fixed 10 V output, 800 mA max, 1.2 V dropout (at 800 mA); SO-8 package but different pinout (IN-GND-OUT). | Higher current capacity suits systems needing >100 mA; not pin-compatible-requires PCB layout change. | Select TLV1117-10CPK only if higher output current and lower dropout at high load are required, and layout revision is acceptable. |
| AP2210K-10W5 | 10 V output, 150 mA max, 0.6 V dropout (at 150 mA); SOT-23-5 package, active-low enable. | Smaller footprint and lower quiescent current (2.5 µA in shutdown), but incompatible enable polarity and no NC pins. | Choose AP2210K-10W5 for space-constrained designs where active-low control aligns with system architecture and 150 mA suffices. |
Compared with TLV1117-10CPK and AP2210K-10W5, UPC29S10GR-E2-A offers unique value in flash-programming applications due to its ±2% accuracy, SOP-8 pinout matching legacy NEC microcontroller reference designs, and integrated saturation protection-critical when operating near dropout.

FAQ
What is the maximum input voltage rating for UPC29S10GR-E2-A?
The absolute maximum input voltage for UPC29S10GR-E2-A is 20 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent device failure. For reliable long-term use, the recommended input range is 11 V to 18 V per the Recommended Operating Conditions-ensuring optimal dropout performance and thermal margin while powering the 10 V output rail.
Does UPC29S10GR-E2-A require external capacitors, and what values are recommended?
Yes, UPC29S10GR-E2-A requires both input and output capacitors. A 0.1–0.47 µF film or high-stability ceramic capacitor must be placed within 2 cm of the INPUT pin to prevent oscillation; a ≥10 µF low-ESR electrolytic or tantalum capacitor is required at the OUTPUT pin to ensure transient stability and ripple suppression. These values are explicitly mandated in the Typical Connection diagram and cautions section of the datasheet.
What happens to the output when the ON/OFF pin is pulled low?
When the ON/OFF pin of UPC29S10GR-E2-A is driven to 0 V (logic low), the regulator enters full shutdown mode: output voltage drops to near 0 V, and quiescent current reduces to 10 µA (IBIASOFF). This state disables all internal circuitry except the enable comparator-enabling ultra-low-power system sleep modes without disconnecting input power.
Is UPC29S10GR-E2-A suitable for automotive applications?
UPC29S10GR-E2-A is rated for Standard quality grade per Renesas documentation, supporting applications such as office equipment, communications gear, and industrial robots-but not automotive or safety-critical systems. Its operating ambient temperature range (−30°C to +85°C) falls short of AEC-Q100 Grade 2 (−40°C to +105°C), and it lacks automotive qualification documentation. For automotive use, consult Renesas' dedicated automotive LDO portfolio.
How does the thermal shutdown feature operate in UPC29S10GR-E2-A?
UPC29S10GR-E2-A incorporates junction-temperature sensing that triggers thermal shutdown when TJ reaches 150°C. At that point, the output is disabled and remains off until junction temperature falls below the hysteresis threshold (~135°C). This protects the die from irreversible damage during overload, poor heatsinking, or high ambient conditions-fully documented in the Absolute Maximum Ratings and Block Diagram sections of the datasheet.
