General Description
LD1117AS50TR General Description
The LD1117A is a LOW DROP Voltage Regulator able to provide up to 1A of Output Current, available even in adjustable version (Vref=1.25V). Concerning fixed versions, are offered the following Output Voltages: 1.8V, 2.5V, 2.85V, 3.3V and 5.0V. The 2.85V type is ideal for SCSI-2 lines active termination. The device is supplied in:SOT-223, DPAK and TO-220. The surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. Only a very common 10µF minimum capacitor is needed for stability. Only chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 2% at 25 °C.
LD1117AS50TR Maximum Ratings
| Symbol | Parameter² | Value | Unit |
| VIN | DC Input Voltage | 10 | V |
| PPtot | Power Dissipation | 12 | W |
| Tstg | Storage Temperature Range | -40 to +150 | |
| Top | Operating Junction Temperature Range | 0 to +125 |
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied. Over the above suggested Max Power Dissipation a Short Circuit could definitively damage the device.
