onsemi KA431S
The KA431S / KA431SA / KA431SL are three−terminal adjustable regulator series with a guaranteed thermal stability over the operating temperature range. The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 W.| Part No. | KA431S |
