Product details

Overview

RP114Q302D-TR-FE from Ricoh Electronics is a 3.0 V fixed-output, 300 mA CMOS low-dropout (LDO) regulator in SC-88A package with ±1.0% output voltage accuracy at 25°C, 0.22 V typical dropout at 300 mA, 50 µA typical supply current, and 75 dB ripple rejection at 1 kHz - designed for battery-powered portable communication equipment requiring stable, low-noise power.

For engineers reviewing the RP114Q302D-TR-FE datasheet, RP114Q302D-TR-FE pinout, RP114Q302D-TR-FE application, or RP114Q302D-TR-FE equivalent, this page delivers verified electrical specs, SC-88A terminal mapping, real-world use cases in handheld devices, and validated alternative LDOs with documented functional trade-offs.

Technical Context

The RP114Q302D-TR-FE implements a CMOS-based error amplifier with internal voltage reference and low-ON-resistance output transistor to achieve ultra-low dropout and high PSRR. Its "H"-active CE pin enables fast enable/disable control, and the integrated fold-back short-circuit protection limits output current to 60 mA under fault conditions.

This device operates across −40°C to +85°C with input voltage range 1.4 V to 5.25 V and supports ceramic output capacitors ≥1.0 µF. The D-suffix variant includes auto-discharge functionality, actively discharging the output capacitor when disabled to prevent residual voltage hold-up.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0 V (±1.0% at 25°C; ±3.0% over −40°C to +85°C)
Max Output Current	300 mA continuous - sufficient for powering RF transceivers or microcontrollers in portable systems
Dropout Voltage	0.22 V typ. at 300 mA - enables regulation from 3.22 V input, extending battery runtime in single-cell Li-ion or 3×AA applications
Ripple Rejection	75 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog or RF circuitry
Supply Current	50 µA typ. active / 0.1 µA typ. standby - minimizes quiescent drain in always-on subsystems
Input Voltage Range	1.4 V to 5.25 V - compatible with wide-input PMIC outputs and legacy 3.3 V/5 V rails
Thermal Shutdown	Integrated - protects against sustained overload or poor PCB thermal design

Pinout & Package

RP114Q302D-TR-FE uses the SC-88A (SOT-457) 5-pin surface-mount package, measuring 2.0 mm × 2.1 mm × 0.9 mm, with exposed pad not electrically connected (NC). Pin 2 is no-connect; all other pins are electrically functional and require correct routing per the pin map below.

Pin/Terminal	Circuit Role	Design Meaning
1	CE	Chip Enable input - "H"-active logic; drives output to regulated state when ≥1.0 V applied
2	NC	No connection - must be left floating; no internal bond or circuit tie
3	GND	Ground reference for all internal circuits and output return path
4	VOUT	Regulated 3.0 V output - requires ≥1.0 µF ceramic capacitor placed adjacent to pin
5	VDD	Input power supply - must be decoupled with ≥1.0 µF ceramic capacitor near pin

Key Features

Feature	Design Value
Auto-discharge function	Actively discharges output capacitor to <0.1 V within 100 µs of CE deactivation - prevents unintended wake-up in sleep-mode systems
Ceramic capacitor compatibility	Stable with ≥1.0 µF X5R/X7R MLCCs - eliminates need for costly tantalum or aluminum electrolytics
Low temperature drift	±80 ppm/°C output voltage drift - maintains tight regulation across industrial temperature range
Fold-back current limit	60 mA short-circuit current - limits power dissipation during output faults without latch-up
High PSRR at 10 kHz	65 dB minimum - preserves signal integrity in audio codec or ADC reference supplies

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP2112K-3.0TRG1	Fixed 3.0 V, 600 mA, SOT-23-5, 300 mV dropout at 600 mA, no auto-discharge	Lacks auto-discharge; higher max current but larger package and higher quiescent current (65 µA)	Select when higher output current is required and CE-controlled discharge is unnecessary
MCP1700T-3002E/TT	Fixed 3.0 V, 250 mA, SOT-23-3, 178 mV dropout at 250 mA, no CE pin or auto-discharge	3-pin solution without enable control; lower current rating and no discharge capability	Select for cost-sensitive, always-on applications where CE control and discharge are omitted

Compared with AP2112K-3.0TRG1 and MCP1700T-3002E/TT, RP114Q302D-TR-FE uniquely combines SC-88A miniaturization, 300 mA capability, H-active CE, and auto-discharge - making it optimal for space-constrained, battery-gated portable systems requiring rapid, safe power sequencing.

FAQ

What is the maximum allowable input voltage for RP114Q302D-TR-FE?

The absolute maximum input voltage is 6.0 V, but the recommended operating range is 1.4 V to 5.25 V. Operation above 5.25 V is limited to ≤500 hours cumulative at 5.5 V per reliability testing; sustained use beyond 5.25 V risks accelerated degradation and reduced lifetime.

Does RP114Q302D-TR-FE require an external resistor network to set output voltage?

No. RP114Q302D-TR-FE has an internally fixed 3.0 V output; no external resistors are needed. The "302" in the part number denotes 3.0 V (30) with "2" indicating the D-suffix auto-discharge variant - output voltage is factory-trimmed and non-adjustable.

Can RP114Q302D-TR-FE drive a 300 mA load continuously in SC-88A package?

Yes, but thermal derating applies: at 25°C ambient, the SC-88A package supports 300 mA only if input-to-output differential is ≤0.5 V (e.g., VIN ≤ 3.5 V). At higher differentials or elevated ambient temperatures, output current must be reduced per the 380 mW power dissipation limit and θ_JA = 263°C/W thermal resistance.

How does the auto-discharge function behave during CE deactivation?

When CE transitions from "H" (≥1.0 V) to "L" (≤0.4 V), the internal N-channel MOSFET connects VOUT to GND, discharging the output capacitor to <0.1 V within 100 µs (typical). This prevents back-powering of upstream circuitry and eliminates leakage paths that could delay system sleep entry.
