3PEAK TPL903233-S5TR

TPL903233-S5TR is a fixed 3.3 V member of the 3PEAK TPL9032 linear-regulator family. It delivers up to 300 mA when input headroom and thermal limits permit. Its low noise and high power-supply rejection suit local analog and imaging rails; the active-high EN pin allows controlled startup.

• Fixed nominal 3.3 V output with ±2% accuracy across specified line, load and temperature conditions.
• Recommended input range 1.75 to 5.5 V; regulation also requires VIN above VOUT plus load-dependent dropout.
• 300 mA output-current rating within dissipation and junction-temperature limits.
• Typical ground-pin current 120 µA at zero output load under manufacturer test conditions.
• Active-high EN; typical active output-discharge resistance 290 Ω when disabled.
• Reverse-current, current-limit and thermal-shutdown protection.
• Use a 1 µF or larger ceramic output capacitor; follow manufacturer ESR and derating limits.

LCDCHIP registers SC-74A, SOT-753. The manufacturer orderable suffix S5TR specifies SOT23-5. Confirm land pattern, orientation and dimensions against the 3PEAK package drawing; the catalog JPG is illustrative.

Pin assignment follows the 3PEAK TPL9032 SOT23-5 top-view drawing.

Check load-dependent dropout, transient response and dissipation in the manufacturer tables for the actual circuit.

No internal alternative is linked because an exact LCDCHIP substitute has not been verified through the product API. Match 3.3 V output, 300 mA capability, SOT23-5 pin map, input range, EN behavior, output-discharge behavior, PSRR, capacitor stability and thermal performance.

The 3PEAK TPL9032 data sheet lists TPL903233-S5TR as a 3.3 V SOT23-5 orderable with marking L8Z. Its pin-function, electrical and application tables govern the design values above.

Check full TPL903233-S5TR order code, marking L8Z, lot traceability, SOT23-5 dimensions and pin-1 orientation against 3PEAK documentation. A generic package JPG cannot establish device identity.

Place input and output bypass capacitors close to the pins. Verify VIN above both the 1.75 V minimum and the voltage needed for 3.3 V regulation at the required load. Check capacitor effective value, output-discharge behavior, power dissipation and junction temperature before design release.
