Product details

Overview

MIC5202-4.8BM from Microchip Technology is a fixed-output 4.8 V low-dropout linear regulator with 150 mA output current, 350 mV dropout voltage at full load, and ±2% output voltage accuracy. It operates from 2.5 V to 24 V input and is used in battery-powered instrumentation and portable medical sensors requiring stable low-noise supply.

For engineers reviewing the MIC5202-4.8BM datasheet, MIC5202-4.8BM pinout, MIC5202-4.8BM application, or MIC5202-4.8BM equivalent, key selection factors include dropout voltage at 150 mA, thermal shutdown behavior, reverse-battery protection, and SO-8 package thermal performance in compact PCB layouts.

Technical Context

The MIC5202-4.8BM integrates a PNP pass transistor, internal bandgap reference, error amplifier, and thermal shutdown circuitry. It delivers regulated 4.8 V output without external capacitors for stability, supporting operation down to 1 µF ceramic output capacitance.

Designed for single-supply systems, it features reverse-battery protection to prevent damage during incorrect polarity connection and includes current limiting that folds back above 200 mA to limit power dissipation during short-circuit events.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 4.8 V ±2% - ensures precise biasing for analog front-ends and ADC references.
Max Output Current	150 mA - supports low-power microcontrollers, op-amps, and sensor signal chains.
Dropout Voltage	350 mV @ 150 mA - enables regulation from 5.15 V input when output is 4.8 V.
Input Voltage Range	2.5 V to 24 V - accommodates wide-input industrial and automotive battery systems.
Quiescent Current	120 µA typical - minimizes standby power loss in always-on monitoring circuits.
Thermal Shutdown	Activated at 160 °C junction temperature - protects device during sustained overload or poor heatsinking.

Pinout & Package

Package: SO-8 (Small Outline, 8-pin, 150 mil width), surface-mount, with exposed thermal pad connected to GND for enhanced heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Input voltage supply	Accepts 2.5–24 V; requires local 0.33 µF ceramic bypass capacitor.
2 (GND)	Ground reference	Common return path; connects to thermal pad for thermal management.
3 (EN)	Enable control input	Active-high logic; pulls low to disable regulator and reduce quiescent current to 1 µA.
4 (OUT)	Regulated output	Delivers 4.8 V ±2%; requires ≥1 µF ceramic output capacitor for stability.
5–8 (GND)	Additional ground terminals	Multiple GND pins improve noise immunity and reduce ground impedance in high-frequency switching environments.

Key Features

Feature	Design Value
Reverse-battery protection	Withstands –24 V input without damage - eliminates need for external series diode in battery-reversal-prone designs.
Foldback current limiting	Reduces output current to ~50 mA during short-circuit - limits junction temperature rise and avoids thermal runaway.
Low-noise operation	40 µV_RMS output noise (10 Hz–100 kHz) - suitable for precision analog signal conditioning without added filtering.
Stable with ceramic capacitors	Supports 1 µF–10 µF X7R/X5R ceramics - reduces board area and cost vs. tantalum or electrolytic alternatives.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1702T-4802E/MB	Same 4.8 V output, but 250 mA rating and 600 mV dropout at full load; no reverse-battery protection.	Lacks reverse-polarity hardening - unsuitable for field-serviceable battery compartments.	Prefer MIC5202-4.8BM where reverse-battery exposure is possible.
TPS76348DBVR	4.8 V output, 150 mA, 300 mV dropout, but requires minimum 2.2 µF output capacitance and lacks enable pin.	No EN control complicates power sequencing in multi-rail systems.	Choose MIC5202-4.8BM when active enable and low-ESR ceramic compatibility are required.

Compared with MCP1702T-4802E/MB and TPS76348DBVR, the MIC5202-4.8BM uniquely combines reverse-battery protection, EN functionality, and stable operation with 1 µF ceramic output capacitors - critical for space-constrained, field-deployed medical and industrial devices.

FAQ

What is the maximum input voltage rating for the MIC5202-4.8BM?

The MIC5202-4.8BM supports an absolute maximum input voltage of 24 V. Operation beyond this level risks permanent damage to the internal PNP pass transistor and bandgap reference circuitry. The device is rated for continuous operation from 2.5 V to 24 V input, making it suitable for 12 V and 24 V industrial bus systems with transient margin.

Does the MIC5202-4.8BM require an external capacitor on the output pin?

Yes, the MIC5202-4.8BM requires a minimum 1 µF ceramic output capacitor for stability, with recommended values between 1 µF and 10 µF (X5R or X7R dielectric). Unlike older LDOs, it does not require tantalum or electrolytic types, reducing footprint and improving reliability. The MIC5202-4.8BM remains stable with ESR as low as 10 mΩ.

How does the enable (EN) pin function on the MIC5202-4.8BM?

The EN pin on the MIC5202-4.8BM is active-high and controls regulator output state. When pulled to ≥2.0 V (with respect to GND), the MIC5202-4.8BM operates normally. When pulled to ≤0.4 V, it disables the output and reduces quiescent current to 1 µA. This feature enables precise power sequencing and ultra-low-power sleep modes in battery-operated systems using the MIC5202-4.8BM.

Can the MIC5202-4.8BM survive reverse battery connection?

Yes, the MIC5202-4.8BM includes integrated reverse-battery protection and withstands –24 V applied to the IN pin without damage or latch-up. This eliminates the need for an external series diode in applications such as field-serviceable medical devices or industrial sensors where battery polarity reversal is possible during maintenance. The MIC5202-4.8BM continues to protect downstream circuitry even under sustained reverse-voltage conditions.

What thermal considerations apply to the MIC5202-4.8BM in SO-8 package?

The MIC5202-4.8BM in SO-8 uses an exposed thermal pad tied to GND. With standard 2 oz copper and 2 cm² of 2-layer thermal relief, its θ_JA is 120 °C/W. At 150 mA and 20 V input (18 V dropout), power dissipation reaches 2.7 W - requiring careful layout. Derating is mandatory above 85 °C ambient; thermal shutdown activates at 160 °C junction temperature to protect the MIC5202-4.8BM.
