Product details
Overview
TCR15AG33,LF from Toshiba Electronic Devices & Storage Corporation is a 1.5 A CMOS ultra-low-dropout linear regulator with fixed 3.3 V output, ultra-high ripple rejection (95 dB @ 1 kHz), and fast load transient response (±100/115 mV). It features overcurrent protection, thermal shutdown, auto-discharge, and operates from −40°C to +85°C - ideal for space-constrained portable power rails in cellular phones and wearables.
For engineers reviewing the TCR15AG33,LF datasheet, TCR15AG33,LF pinout, TCR15AG33,LF application, or TCR15AG33,LF equivalent, this device delivers verified 3.3 V regulation at up to 1.5 A with <120 mV dropout at full load, WCSP6F package compatibility, and stable operation using ≥4.7 μF ceramic input/output capacitors and ≥1.0 μF bias capacitor.
Technical Context
The TCR15AG33,LF uses a CMOS-based LDO architecture with separate VBIAS supply (2.5–5.5 V) enabling high PSRR and low quiescent current (25–40 μA). Its control logic supports ON/OFF via a dedicated CONTROL pin with pull-down capability and under-voltage lockout (0.5–0.65 V threshold).
It implements SENSE pin feedback for fixed-output variants to compensate PCB trace voltage drop, and integrates auto-discharge (10 Ω on-resistance) and inrush current reduction - critical for battery-powered systems requiring clean power sequencing and low standby leakage (≤1 μA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1.0% (typ. accuracy), enabling direct replacement of standard 3.3 V logic rails without external resistors. |
| Max Output Current | 1.5 A continuous - sufficient to power SoCs, RF transceivers, or multi-core microcontrollers in compact devices. |
| Dropout Voltage | 193 mV (typ.) at 1.5 A and VBIAS = VOUT + 1.7 V - ensures regulation down to VIN = 3.493 V, supporting single-cell Li-ion or 3.6 V supply margins. |
| Ripple Rejection | 95 dB @ 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in ADCs and RF sections. |
| Quiescent Current | 25–40 μA (ON state) - minimizes battery drain during active operation in always-on sensor nodes. |
| Standby Current | ≤1 μA (CONTROL = 0 V) - enables ultra-low-power sleep modes in portable electronics with rapid wake-up capability. |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade portable equipment including handheld medical and test instruments. |
Pinout & Package
TCR15AG33,LF is housed in the ultra-small WCSP6F package (0.8 mm × 1.2 mm, max height 0.33 mm, weight 0.61 mg), optimized for high-density PCB layouts in smartphones and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Regulated output | Delivers stable 3.3 V to load; requires ≥4.7 μF ceramic capacitor placed adjacent to pin for stability. |
| VIN | Main input supply | Accepts 3.493–6.0 V; must be decoupled with ≥4.7 μF ceramic cap near pin to prevent LC resonance. |
| SENSE | Output voltage sense | Connected directly to VOUT pin in fixed-output configuration to enable remote-sense compensation of PCB IR drop. |
| CONTROL | Enable/disable input | Logic-high (≥1.0 V) enables regulation; logic-low (≤0.4 V) disables output and activates auto-discharge path. |
| GND | Power ground | Common reference for VIN, VOUT, CONTROL, and VBIAS; requires low-impedance plane connection for EMI control. |
| VBIAS | Bias supply input | Provides internal circuitry bias (2.5–5.5 V); requires ≥1.0 μF ceramic capacitor to GND for PSRR and transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 193 mV typ. at 1.5 A enables use with tight input margins (e.g., 3.6 V Li-ion nominal → 3.3 V rail). |
| High PSRR | 95 dB @ 1 kHz rejects noise from buck converters, preventing coupling into sensitive analog/RF circuits. |
| Fast load transient | ±100/115 mV deviation @ 0.01 A ↔ 1.5 A step ensures stable core voltage during CPU burst activity. |
| Auto-discharge | 10 Ω on-resistance safely discharges VOUT when disabled - eliminates residual voltage that could cause latch-up in downstream ICs. |
| Thermal & overcurrent protection | Integrated shutdown prevents damage during overload or poor heatsinking - no external components required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6215D332MR-G | 3.3 V fixed, 1 A max output, SOT-25 package (2.9 × 2.8 mm), 250 mV dropout @ 1 A | Larger footprint, lower current rating, no VBIAS pin or auto-discharge | Select when cost sensitivity outweighs size/current requirements and auto-discharge is not needed. |
| Rohm BD3572EFJ-ME2 | 3.3 V fixed, 1.5 A, HTSOP-J8 package (4.0 × 4.0 mm), 250 mV dropout @ 1.5 A, no VBIAS pin | 5× larger footprint, higher thermal resistance, lacks bias-supply isolation and PSRR performance | Choose only if existing layout accommodates HTSOP-J8 and PSRR >80 dB is not required for signal chain integrity. |
Compared with TCR15AG33,LF, both alternatives offer fixed 3.3 V output but lack its ultra-small WCSP6F footprint, VBIAS-supplied architecture for superior PSRR, and integrated auto-discharge - making TCR15AG33,LF uniquely suited for next-generation compact, battery-sensitive designs demanding high noise immunity and rapid power-state transitions.

FAQ
What is the maximum input voltage rating for TCR15AG33,LF?
The absolute maximum input voltage (VIN) for TCR15AG33,LF is 6.0 V. Operation above this level risks permanent damage. For reliable 3.3 V regulation, VIN must remain ≥ (VOUT + VDO) - minimum recommended is 3.493 V at 1.5 A load per the dropout specification. Always observe derating guidelines in Toshiba's Semiconductor Reliability Handbook when designing for thermal margin.
Does TCR15AG33,LF require an external resistor network to set output voltage?
No, TCR15AG33,LF is a fixed-output variant delivering 3.3 V without external resistors. Its marking "3K3" confirms the fixed 3.3 V configuration. Unlike the adjustable TCR15AGADJ version, it uses internal trimming and connects the SENSE pin directly to VOUT - eliminating resistor tolerance errors and PCB layout complexity for standard 3.3 V rails.
How does the VBIAS pin function in TCR15AG33,LF and what voltage range is supported?
The VBIAS pin supplies independent bias power to the internal CMOS control circuitry, decoupling regulation performance from VIN fluctuations. For TCR15AG33,LF (VOUT = 3.3 V), VBIAS must be ≥ (VOUT + 1.4 V) = 4.7 V and ≤ 5.5 V. A ≥1.0 μF ceramic capacitor is mandatory between VBIAS and GND to maintain PSRR and transient stability.
Can TCR15AG33,LF be used without the SENSE pin connection?
No - for fixed-output variants like TCR15AG33,LF, the SENSE pin must be connected directly to the VOUT pin per Toshiba's application note. This connection enables remote-sense compensation of PCB trace resistance, ensuring output voltage accuracy at the load rather than at the regulator die. Omitting this connection degrades regulation accuracy and violates the validated design configuration.
What is the typical quiescent current of TCR15AG33,LF in active operation?
The typical quiescent current (IB(ON)) of TCR15AG33,LF is 25 μA at 25°C, rising to a maximum of 40 μA across −40°C to +85°C. This ultra-low IB(ON) enables extended battery life in always-on portable systems. When disabled via the CONTROL pin, standby current drops to ≤1 μA - confirmed in the Electrical Characteristics table under IBIAS(OFF) and IIN(OFF) parameters.
