Adjustable and fixed low drop positive voltage regulator

Datasheet

production data

Features

• Low dropout voltage (1 V typ.)

• 2.85 V device performances are suitable for

SCSI-2 active termination

• Output current up to 800 mA

• Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V,

3.3 V, 5.0 V

• Adjustable version availability (V

REF

= 1.25 V)

• Internal current and thermal limit

• Available in ± 1 % (at 25 °C) and 2 % in full

temperature range

• Supply voltage rejection: 75 dB (typ.)

Description

The LD1117 is a low drop voltage regulator able

to provide up to 800 mA of output current,

available even in adjustable version

REF

= 1.25 V). Concerning fixed versions, are

offered the following output voltages: 1.2 V, 1.8 V,

2.5 V, 2.85 V, 3.3 V and 5.0 V. The device is

supplied in: SOT-223, DPAK, SO-8 and TO-220.

The SOT-223 and DPAK surface mount packages

optimize the thermal characteristics even offering

a relevant space saving effect. High efficiency is

assured by NPN pass transistor. In fact in this

case, unlike than PNP one, the quiescent current

flows mostly into the load. Only a very common

10 µF minimum capacitor is needed for stability.

On chip trimming allows the regulator to reach a

very tight output voltage tolerance, within ± 1 % at

25 °C. The adjustable LD1117 is pin to pin

compatible with the other standard. Adjustable

voltage regulators maintaining the better

performances in terms of drop and tolerance.

LD1117 adjustable: application note 7 LD1117 LD1117 adjustable: application note The LD1117 adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between the OUT and ADJ pins. IADJ is 60 µA typ. (120 µA max.) and ∆IADJ is 1 µA typ. (5 µA max.). R1 is normally fixed to 120 Ω. From Figure 9 we obtain: VOUT = VREF + R2 (IADJ +IR1) = VREF + R2 (IADJ +VREF /R1) = VREF (1 + R2 / R1) + R2 x IADJ.
